Am I too paranoid ?

I don't know if its a real gut instinct or im too paranoid. I would also like to mention i have severe anxiety and i tend to get paranoid about alot, not just my boyfriend. I wanna use one example that happened last night.. my boyfriend hardly shaves down there. Of course he bathes and showers but he never really shaves. Maybe just trims so that it's still a 'bush' (sorry tmi 😂). He hadn't properly shaved for a few months and he came over my house for the first time in a few days yesterday which was sunday and it was completely shaven. The Friday before that he had went out and got back home at 1:30 in the morning. So i put 2 & 2 together and I started accusing him of being with another girl. He started saying I'm too paranoid and that it's his body, he can shave if he wants to "its not called cheating its called hygiene". But the only reason I accused him because I found it weird how he hadnt shaved down there in a while, and then all of a sudden when I don't see him for a few days, he goes out Friday night and all of a sudden he's shaven. Its not the first time ive accused him and im scared im going to ruin things and our chance of being a family (im 30 weeks pregnant) because im too paranoid. He keeps telling me how he only wants me, that he's not even talking to any girls to be able to arrange to meet up with one, but he seems really calm when saying all this telling me he can't make me believe him, how I'm only going to drive myself crazy by thinking things all the time. He said he'd have to be sick in the head to do that to me when im having his baby. He says he understands how it looks when he doesn't spend time with me for a few days when he's with friends and when he goes out at night but he's actually not doing anything wrong. Does he sound 'suspicious' to you or does it sound like I'm just the one who's just way too paranoid? I don't mind being told how it is because if it is just me I need to stop before I mess things up
