Is it possible..? (sorry in advance for gross details)

I've had ammenhorea for about two years and yesterday (after feeling VERY bloated/constipated) I noticed some blood in the toilet.  It wasn't much, but it was there, and I was so excited that I burst into tears---when I told my parents my mom started crying, my dad excitedly congradulated me, and they both hugged and kissed me over and over again.  We all felt so relieved. 

When I had to use the bathroom again though, there was no blood. None.  Today I haven't noticed any either.

So I'm wondering if I actually was beginning my cycle, or if it was something else.  I know I haven't had one in so long, but I still haven't forgotten the different ways my body used to feel during those times, and everything (unpleasant or not) felt "right" yesterday.  Because I haven't had one in so long, is it possible for it to be VERY light and only last one day?  

Thanks for reading, I appreciate anyone's insight.

*Cough* This might sound really nasty, but it could be an anal fissure. No pain or anything, just bleeding. Easy to cause, quick to heal.

I guess it could be possible.  In the spirit of too much information, I used to have two periods a month, both of which lasted 8-10 days.  My doctor put me on birth control pills, and my first period with the new hormone arrangement only lasted one or two days and was really light. 

If that's not the case, wistfulxthinking could be right.  There are a number of things that could cause blood in the toilet.  Let's hope for the best and maybe we'll find out next month!

I always know when my period is coming when, for the week or so before, i get some occasional white/clear discharge.  If you had anything like that, I'd say perhaps it was a one-day period.

*shrug*  I don't know.  Just keep it up and hope that next month you'll see something again.  Don't give up!

Yes I think its very possible, my doctor told me when my period returns it will probably be light and not last very long in the beginning.

I'm obviously not any kind of expert on this, but it seems to me that there isn't any reason you couldn't start regaining your period with irregular 'spotting' instead of a very normal flow. Eat healthy and take good care of yourself, and hopefully next month!!!

Thank you very much for all of your replies. wistfulxthinking I think there's a possibility you could be right, because (bleah, I know) I've often been getting constipated.  Before I saw the blood in the toilet that day, I had been constipated, gassy, and bloated all day, and had finally gotten myself to go a little bit and let out some gas too (ugh lol).  My mom, aware of this, asked me later if I thought it came from my anus, and I'm honestly not sure.  When it happened I wondered this too, but I'm really trying to be optomistic.

Once again, last night, I waited too long to eat my dinner and ended up filling up on too many vegetables (ED says, well you need more FIBER, and vegetables aren't "scary" so just eat a bunch of them with everything else).  I had felt hungry all day pretty much, but I was too stubborn to eat with my family at dinner time (they had said 6 o'clock, but were ready around 5, so I got panicky and ended up taking a walk). It was 9 by the time I felt "ready" to eat, and at that point I had only had about 400-600 calories so far.  Needless to say, I was very hungry, and there were so many vegetables (my "safest" munching foods..) in the fridge, so I just basically inhaled them.  I know I'm supposed to get up to 2500 AT LEAST everyday, but I didn't start thinking about eating higher calorie things until I started feeling ill, and by that time it was about 11 anyway.  In addition to eating more regularly, I'm also trying to get more sleep too (I tend to deprive myself of that during school) so I just felt defeated mentally and phsically.  Sleeping was almost impossible last night because my entire body was aching all over, I was constipated again, I felt like I was ready to throw up, I felt dehydrated but too full to drink, and I was getting severe chills.  My mom didn't know, but when she got up to take me to school, I told her about everything.  She's very understanding, and instead of scolding me for being stubborn yesterday, she just told me to treat this as a learning experience, and to take better care of myself today.  I stayed home, I've already eaten a bigger breakfast than normal, and I plan on resting instead of doing a bunch of meaningless compulsive excercises.  Hopefully I'll get to bed at a decent hour and feel better tommorow.  Its weird though, because my body still aches all over, and not like regular muscle fatigue.  Its more like weights have been put all over my body and they're pulling at my legs, lower back, and head.  My chills are gone, along with most of the nausea, but now I'm wondering if I'm actually coming down with something.  Hmm...Prom is this Friday...I wonder if I'm just unconsiously stressed or something.  Heh, I don't really know why I wrote all this..maybe you guys can once in a while just yell at me or something to be smarter or something lol.

Anyway, thanks again for all of your input.  I'm going to start writing a schedule out again for myself to plan out my activities and eating times.

Kate777, if this happens again and you're still not sure if it's your period or some other type of bleeding, you should look closely at the COLOR of the blood.  Menstual blood has a different color than internal blood.  I have amennorhea, too (caused by PCOS), but I can usually tell if it's my period coming on, no matter how long it's been since I've had it.  My husband has hemorroids, and his doctor told him to look a the color if he ever has blood, so he can tell if it's internal bleeding or a bleeding hemorroid.  Hope this helps a bit, and good luck. 

Yeah, ejmph4,  I took that into consideration too.  As I recall, initially the blood appeared dark red, but then later it was more of a lighter crimson color---so I'm still not sure what to make of it.
