Your opinion on if this is implantation bleeding or period
I had an unmedicated, unmonitored IUI done on July 15. I had had my period start on June 28, and I didn't start testing with the ovulation kit until day 14 after that, and I didn't have a surge, but it looked like I had one on the 17th day, July 14, so I went in on the 15th for the procedure.
During it, the doctor asked the nurse to come over and said "something's not right here", but he never told me what he meant. It pinched a lot and I wondered if maybe my cervix wasn't open and I hadn't really ovulated.
July 29 was when they wanted me to come in for a blood test. I got what seems to be a period on that day, even though that was about 2 days past the latest that I thought my period would be due. I realized after I did the IUI that I wasn't ready for this and didn't really want it to work, and I stressed unbelievably ever since. I also have done some exercises I usually don't do, like swimming, so I don't know if that could have thrown my period off.
I am 39 years old, will be 40 at the end of September. My periods have been pretty irregular this year in the sense that they have come anywhere from 25 to 30 days. In May I had a 30 day cycle. My ovulation seems to be irregular as well, as once it seemed to be early and another time, it seemed late.
The first day of what appears to be my period was quite heavy with clots, red, yesterday was pretty typical second day of a period for me, and cramping and everything, and today I've had it but it seems to be tapering a little bit in heaviness, which is not atypical for me with a period, but still, I'm scared it's really implantation bleeding and not my period.
I've been testing many days with Clear Blue HPT, and they've all been negative, the last one I did was the 28th and that was negative. I also went to Planned Parenthood yesterday and they tested my urine and said it was negative. I did tell them my fears that this is just implantation bleeding and they did tell me to take another home test on August 5th to be totally sure, though the nurse was pretty certain that the testing they did was accurate.
Of course I will do the testing on August 5th, but I was wondering what your opinion was, do you think that this is implantation bleeding? My periods generally aren't that heavy anyway and they do only last about 5 days, in fact the 5th day is usually just a bit of brown spotting. I've also lost some weight because of my anxiety, not sure if that could affect anything.
