35 years old, period normally 28 day cycle, this cycle I was 5 days ate on 6th day I had pink spotting, day 7 I had red blood with mucous, but it is only small amount on pad, I get a majority of the blood when I wipe, Husband and I are TTC. I have had trouble in the past getting a pregnancy test to show positive. Thoughts if this is a period or could we be pregnant?
