I have been on the pill for a number of months now and I take it religiously every day, yet every time I have sex I still convince myself I am pregnant. 3 weeks ago I had sex however he did not ejaculate inside me, yet now I have tender breasts. Could this just be a side effect Of the pill? Any advice on how not to be so paranoid about pregnancy as it is now starting to consume my life and get in the way of my relationships, thanks.
