Mid cycle bleeding, now no AF?

Lisa

Cycles are normally 26-29 days.

Last was normal. Positive ovulation on day 10 (odd because it is usually day 15 for me). We are TTC so multiple attempts to get pg. Then 5 days after ovulation i spotted bright red for 3 days. I was really crampy and bloated. Felt weak. If i dont count the spotting as AF I am now on day 42. With no AF in sight. Negative pregnancy test at home. Any advice/feedback?
