Mid cycle bleeding at ovulation is pretty common, as is pain. It usually goes away after a few months. You might want to make sure your thyroid replacement is adequate by getting thyroid blood tests. If the bleeding persists, an ultrasound, and a blood test on day 21 for progesterone to make sure you are ovulating, would be reasonable. Your most fertile period of time, assuming a 28 day period, is probably days 11-18, and intercourse every couple of days is more than adequate. Good luck!
I never use to have this, but I have had it for 3 cycles...when I O, have bloody ewcm, then ewcm goes away and have spotting for a day or two then gone. I called my RE and she said it was just from O'ing.
I'm soooo sorry...I didn't realized I was on the MD question board...oops
