Have namechanged due to severe ickyness of what follows.
I have no reason to believe I am/was pregnant. Am sexually active but have been using condoms and have had no apparent 'accidents'.
I don't have regular periods so I don't keep track of gaps but don't think it's been more than 5/6 weeks since last one, which is normal for me.
I have always had heavy periods (have to use super plus extra tampons and still leak at night) with lots of clots. But I have NEVER had a period like this!
I have been losing blood for at least 2 weeks, probably more like 3. The first week or so was like a 'normal' period (as above). But over the past few days I have passed several large pieces of tissue. Most has been smooth like clots but up to 4 inches in length. Another piece was a much more solid bit of flesh, not as dark as the clots. It was just under an inch long, about half an inch wide and half an inch deep.
Yesterday I had a super plus extra tampon in (plus some extra toilet tissue stuffed up) but after an hour and a half I had to run to the toilet because I had blood running down my legs. I felt quite light-headed at the time but feel ok now.
So, what is/was this? When I try to look up my symptoms online, it comes up miscarriage. But that's assuming that the person was pregnant in the first place. I have no reason to think I was pregnant (had no symptoms).
I do want to try for DC3 next year but now I'm really worried that there is something wrong with me/my fertility.
What could this be and is it likely to happen again?
