What am I experiencing? tmi

OK so I'm not sure what's going on. This has happened twice now. Two times I was sure I was pregnant...sometimes you just know things. I took tests, all were negative but one had just a faint line that could've been positive (I recommend digital now). I had had my period the month before, but was running late this time around. My periods were like clockwork, so I knew something was up. I then got what at first I thought to be a late period, but it was so different. I was in so much pain and it was so thick and stringy/clotty. I have never had pains as bad as this in my life. When talking about it with a friend, she mentioned maybe I did have a mc very early (4-5 weeks?) I was upset at the thought, but since I didn't know I just went on with it. Then, about 6 months later, for no apparent reason I just didn't get a period that month. We tested a few times, again all negative, but I have NEVER in 10 years missed a period or hardly ever been late. I decided if I didn't get one the following month (april 09) I'd go to a dr. Sure enough, April rolls around and I have one just fine for the next few months. Then, this month rolls around and is late again. I never thought anything of it, then it shows up and it's the same as the one 6 months ago. Heavy, clotty, so much pain in my abdomen and pelvic region. IDK what I am experiencing, if it's a mc or just a fluke. I know every woman is different, but does anyone have any ideas? We recently moved here from WV and I have yet to find my way around to getting to know a Dr. or an ob/gyn as my husband and I want to start ttc this fall. I'm just so confused!

could very well be a MC or it could be a really heavy period, and the reason for it being late could be stress
have you been under alot of stress?

i used ot have horrible periods in oregon and when i moved to montana they got better, i guess different elevations could put more pressure on your uturus and make cramps worse. also clots can be caused by lack of exercise and WATER!!

Actually my stress load has lifted considerably lately. I have been way happier in the last month than the months prior. I usually never have these very heavy periods, usually just regular flows that's why it has caught me so off guard.

I thought of that, but I've lived here 6 months by now I thought I'd be acclimated. Also I heard going down in elevation was better than adjusting to going up, but who knows. I have been moderately active, could obviously be more so, and have dramatically increased my water intake lately. I barrel race horses so I'm trying to shed a few vanity pounds anyway to shave off a few seconds. I guess I'll just have to wait and see. It just worries me because my husband and I have just decided to take our honeymoon (a little late) and ttc while there....I don't want something to be wrong.
