I started my period on the 8th of this month and it was abnormal. It wasn t heavy and it lasted two days then on the third day I spotted for an hour then it stopped for a day then it happened again on the 12th and that was the last day I bleed. Yesterday I was taking a shower and felt some tightening in my lower abdominal area but didn t think anything of it so when I got out the shower I bent over to get my clothes and felt like I had to pee so I used the bathroom and when I wiped I realized there was a small amount of blood but that was the only time. What could it be? Me and my husband do not use protection and the last day we had sex was this past Sunday.
