Drugs does effect the sperm. My ex bf & I tried for 3 years to have a healthy baby. We had 2 miscarriages & I had a daughter born with trisomy 13. His sperm was no good. He did so much drugs before we got serious. Now I'm 37 weeks pregnant with my current bf I been with fir a year. I got a genetic test done thank god found out baby is completely healthy & normal. I can't be 100% sure but have a DNA test done they do not lie. Hope the best for you!
Won't know till the end. It's not impossible to get pregnant just because he was on drugs. Might be a less chance but not impossible.
I Googled it and theirs three things in methidone that increase infertility I've been with my boyfriend for two years and never got pregnant and now I am I honestly think maybe it's the affairs
You need to be honest with both of them and do a dna test.
Oh believe me I was very honest I'm not with either one of them I didn't want my ex to buy anything and assume it was his
A dna test is the only way to know for sure unfortunately.
