I've been off of the pill for a month and have been having unprotected sex very often since then. My breast are feeling heavier and sore and I've been nauseous here and there for a few weeks now and have been experiencing some minor cramping, but I haven't noticed any other changes. I don't know if I am pregnant or not because I haven't had withdrawl bleeding yet since I stopped the pill and my period hasn't come either so I'm unsure if pregnancy is even a possibility yet. I just need some advice on what to do or if I should be concerned yet or not. Please help.
