ttc #2 after c-section

Hello ladies, me and my partner are ttc we've been trying for 3 years now and no luck. I had my son who is now 8 by c-section and had complications had a miscarried 3 months after. Been with my current partner for almost 6 years now and going through the motions of test to find out what's going in. It's heartbreaking that I can't give him a baby when he's been bringing my son up like his own. anyone else had trouble after a c-section?
