My cycles are pretty regular. I almost always get my period during the 1st week of every month. I missed November's but didn't think much about it because I was in bed for a week with the flu when I was supposed to get it. And with a fever of 104F I wasn't surprised when it didn't come. ((Sorry if this is a little tmi or a little graphic for some)) By the end of Dec. I started to get paranoid. I don't know if it was my mind playing games with me, but I started getting kind of nauseous after I would eat. I had lost a good bit of weight and having some lower back pain. My discharge has also been very unusual for the last month. Then I started getting horrible cramps. But I was staying with a friend at the time and a stomach virus was going around. Lots of people had diarrhea & were throwing up. So I figured I just had an iron stomach and got off with just some really bad abdominal cramping. I also have a pretty weak lower back and saw the chiropractor for an adjustment, so didn't think much of it. But during the adjustment, it felt like I had a significant "gas bubble" that was really hard in my lower abdomen. Not sure how else to explain it. Again, figured it was from the cramping/fighting off the sickness that was going around. Came home and had lots of heavy bleeding. There were blood clots larger than I've ever seen. All the symptoms pointed to a miscarriage if I got rid of all the strange "coincidences" However I'm still having what feels like light cramping even though the bleeding has stopped. And I just don't feel "right". I don't want to take a pregnancy test unless I miss another period and it's been at least 8 weeks. (I would be 5 weeks now) Because I don't want to freak myself out even more, if it turns out positive. So I guess what I'm asking, is it possible to have had 1 very early miscarriage (or chemical pregnancy as all the other sites are calling it) but still be pregnant? I don't know very much about vanishing twin syndrome. And I have no idea how (or if) losing 1 embryo this early would affect a 2nd one. The would-be father was originally a twin, but lost his other 1/2 before he was born. His mother was surprised to find out she was still pregnant after she lost his twin-- didn't realize there were 2 fetuses in her!
