I had my period Aug 10-15 approximately. I was expecting my period on Sept 11 but i just had a bit of spotting. Then that night we had sex and i was bleeding but it stopped immediately. Sunday moning there was a bit of blood after I worked out, then after i showered there was nothing besides for when I wiped. I also started with cramps what appears to feel like it is behind my belly button on saturday and i continue to get them today. I took a hpt on tuesday could that have been to early to detect a pregnancy
