is it possible?

My boyfriend and I have had sex a lot this month. I'm on the pill and take it around the same time every single day and we still use a condom and he always pulls out when he cums anyway. The condom has never broken. I was just wondering, is it possible for me to give myself pregnancy symptoms from thinking about it too much? I'm a very anxious person so that could be another reason as well. Im supposed to get my period in about 2 days. I'm just curious.
