Fertility HELP

​Don't judge but i was injecting Melanotan 2 into my stomach fat to get tanned last year in August (STUPIDEST THING EVER) and I've just been doing research to now finally find some really bad side effects that weren't on the internet before I started my dosage. They say it leads to infertility so I'm freaking out and I'm thinking maybe that's why I haven't fallen pregnant after 7 months of trying? (I haven't used since last year) Our first baby girl was concieved just after 1 cycle of trying and she's now 2 years old we fell pregnant last year in September but had a miscarriage at 13 weeks (I found out at 3 weeks and stopped all injections but had only done a few so it wouldn't of effected me when I miscarriaged) I let my body heal and started injecting the tan again 8 months later I'm still not pregnant. I need something to boost me and my partners fertility chances, he was on melanotan but we haven't touched it in 5 months. What are some really good successful vitamins we can start taking?
