Been trying for 5 months :(

My husband and I have been trying for 5 months now. I have 2 kids from a previous relationship, both not planned. When I was 17 I got pregnant, had an abortion. I wasn’t for it, still not but my mom was and she was pissed at me so I did. Got pregnant again at 20 years old. I wasn’t sleeping with multiple people this was my 2nd partner. Not sure how I got pregnant. Then my second child I don’t know how she was even conceived because my then boyfriend was very abusive. Now I’m 40 and an in a loving relation, finally!! but can’t conceive. I’ve been taking prenatal vitamins and staying healthy so is my husband. He’s taking male fertility pills. He has an 8 year old son. So I’m sure he’s still fertile. I just started taking MACA, so hopefully that will help. It’s just funny before didn’t want to have children but now I really want to have a child with my husband. I don’t want to have to go thru treatment. Any advise?!
