I had unprotected sex three times 10 days after my period (counting 1 as my first day). a week before my my next period came , i started feeling bloated, irritable/mood changes, breasts are swollen and cramping. On the 29th day i had my period, it was heavy but would only come out when i pee and it only lasted for 2 days. after that, i get a pinkish blood whenever i wipe after i pee. and then 5 days after my period i had blood again and filled a pantyliner. could i be pregnant?
