Losing hope

Can having a c section prevent or make it harder to get pregnant again? I've been trying since October and nothing .... period comes right on time every month 😏☹️ I'm starting to worry a lot why I haven't got pregnant  ... I keep wondering if my csection with my twins who are now 5 has anything to do with it. My bf is 8 years younger then me also so I really don't think he could be sterile or have a problem but who knows I'm just thinking the worst and this is getting depressing 😢
