TTC problems

Paige

Been TTC for 19 months and my partner and I are 23 don’t get why it’s not happened yet, my partner is adamant that it is because I smoke weed, he doesn’t smoke it at all it’s just me I been smoking since I was 14 and only time I stopped smoking was when I was pregnant with my son, it’s been helping me a lot with feeling less stressed about ttc and it’s been helping with my anxiety and depression, I honestly don’t know if that’s the reason I’m not conceiving?
