hi i have some period like bleeding two months in a row, the last time i had sex was may 11 and i had my period last april 28, june 1 & july 3.. i took birth control last may 12 and finished it but two days late when i had sex. i took pt test 6 times all came out negative, today i always feel dizzy, have some mild sharp pains in my stomach and sometimes it feels like theres gas inside my tummy, it makes sound and felt like something is moving. i know it sounds crazy but i feel like im pregnant.. my tummy looks bigger as it seems as before and i gained 5 pounds which is really unusual because eventhough i eat a lot i am always as it is. im thin and i feel like my lower tummy is sticking out. pls help
