Infertility after c section??

Me and my husband have been ttc for over a year now, and I still am not pregnant. I was wondering if any of you ladies who had c sections had a hard time conceiving your second baby?? I’m already taking clomid and taking vitamins but it just isn’t happening. It only took one cycle to get pregnant with my first. They suspect endometriosis as well, and I will be having a lap next month.
