Have been TTC for two years, unexplained infertility. I have regular 28 day cycles and all tests have been clear. Today is day 12 and I got a positive ovulation test this morning. Had sex this evening and straight afterwards had a bleed- TMI alert- bright red, on the duvet cover and some ran down my legs. WTF?? All I can think of is ruptured cyst? But didn't have particularly bad pain, thought it was normal ovulation pain. Any ideas?
