last january 24, me and my bf did it.. at first he was protected but after doin it again that day, he didnt use a condom.we did it again last february 28 using a condom the first time and not on the second. i am expecting my menstruation last February 15, but unfortunatly it didnt came. i tried PT a month after but it was negative... we had another intercourse last march 8, the condom he was using got torn and he said he felt he released it inside but was not really sure about it.. the next day, he adviced me to take pills though i still havnt got my mens.. wat should i do?? am i pregnant? if i use another PT wont the pills affect my hormones and give me the wrong results??
