Being paranoid on who is the dad to my baby.

So at the time i was single . Met 2 guys. 1 guy i was having sex with condoms and it was like once a week and the other without. The other guy with condoms we only had sex once after period and with condom and then my now boyfriend without condoms we had sex more than once after period and for a week. i know its obvious its the other guys baby because we had sex without condoms , he is my now boyfriend now and he knows hes the dad and stuff . Im 27 weeks pregnant. U think its 100% sure its his? Im just paranoid and going crazy that its not and idk why feeling weird about it that i met his mom now and he met my whole family... but i know deep inside its his baby. but we did have lots of sex that week of ovulation he came in me even twice or triple times& the next weeek i got a faint positive test so . Im just being paranoid 😐😐am i just being paranoid?
