Not sure how to feel about this

So hubby and I have a 1 year old, we have unprotected sex all the time, we took a break for about 3 weeks and then recently had sex in my fertile window according to the app, when he was done one of the times he said he kept feeling like he had to finish and then when he pulled out the tiniest amount of cum came out (sorry tmi) I asked him if he came in me and he said he doesn’t know really or think so. My period is due in exactly 7 days and for the last 4 days my boobs have been having sharp pains randomly and yesterday I had creamy cm. I know cm isn’t an indicator but I’m hoping someone can give me an opinion, we don’t mind if we’re pregnant I’m just curious
