Hey hi. My bf and I had sex (Withdrawal method) in august. But i got periods in the next two consequent months i.e in august and september. But from november and december i still dint get periods. Consulted Gyno and got a scanning for my abdomen but she dint turn up by saying anything about pregnancy and i even took a home pregnancy test and it was negative. The change in this two months is that i took a tablets of my asthma overdose.I am bit worried about all this. I am just waiting for your answer.
