What is happening

So I just had sex with my bf this month 2 times. Since the last time we did 2 years ago ( I haven’t done it in a long time cause I got a pregnancy scare). Well I’m freaking out again even tho we used a condom and he didint come I’m 3 days from my period and I’m just worrying about it not coming. My bf says I’m fine but I need more reassurance we used a condom and he didint come and the condoms were not broken afterwards. So I weight 45kg and now I weight 46.7kg and then my boobs are pretty hard and tender and I have stomach pain
