It'll never happen

Well I thought this was my month for sure! But I was wrong. I had spotting 12 13 and 14th light pink and little brown. Also spotted after intercourse either the 14th or 15th. I NEVER spot either this is the first time ever in my life. Also on the 15th had mild cramping lasting only couple seconds. Had alot more frequent bowel movements and I rarely go to the bathroom. Was at work today and felt some lower cramping here and there would come and go. So I went pee and there was bright red also pink on the tissue. 😭😭 I'm just wearing a panty liner and it's still here and there spotting. So I'm out!
