Sex while 38 weeks pregnant😝

So me and my BD haven’t spoken since the beginning of August, his mom wanted a dna test and he agreed with her so we got into a big argument which resulted into him hanging up in my face, so the guy my sister is dating is my BD stepbrother and me and my sister are super close and stay like 5 minutes from each other so of course my BD comes over to her place which is also her bf place so he finally apologizes to me and he tells me that he knows that’s his baby and he’s ready to have a future with me and then baby and then 2 days later he text me but I’m still confused and don’t know what to do but I love him so much and I know he will be a great father and so last night he invites me over and obviously we end up having sex and it was amazing and it felt like everything was gonna be okay but apart of me thinks I’m moving too fast and should not trust him all the way yet
