Hello the last time I had sex was around October November and at the time I was on the pill Leveln and we used condoms. I had my period normally in november and december but in december I was advised to change pills to a POP Noriday which I took one packet and then stopped on January the 12th because I am not currently sexually active. I have not had my period since December.... but how can I be pregnant? And would I not have symptoms by now apart from missed period?
