Had a small hcg injection of 1000 iu before ovulation and the next day i started bleeding, I think I did have a small LH surge as it showed up on a test the next morning after the bleeding but all other test have been neg. I'm hoping this is just ovulation bleeding but I have had some clots along with it small ones it has went from dark pink light pink brown and back to the almost red with the clots. I was trying to conceive and was wondering if it is still possible. I had the spotting on cycle day 14 and now its cycle day 16 and still have the spotting and bleeding. Is it possible to have heavy ovulation bleeding due to the hcg shot.
