possibility of being pregnant?

A.

So around christmas I had my period and within a few days after, me and my bf had sex and he told me he started to cum then pulled out. Recently we both said we wanted to have a baby and hes came in me many times but it was 3-5 days before my period starts (in 2 days now). Ive also been showing some known signs of pregnancy at about 4 weeks (around christmas) like nausea in the morning and after I eat, headaches, cramps (could be my period), major breakouts, swollen & sensativ breasts, bloating, cravings, terrible mood swings, fatigue, ect. I've also just had that feeling that I may be and I've never been like this with my periods. Help? i havent taken a test yet either
