How long TTC?

Hello everyone. I'm 20 yrs old and I found out I was pregnant last December but in February I had a miscarriage 💔. I carried my baby 10 weeks and 3 days. My husband and started trying again at the end of May....nothing so far. Last time it took me 1 month after getting off my birth control...I'm just wondering if there is something wrong with me that I haven't gotten pregnant yet? Anybody else experience anything similar to this?
