TTC for 8 months.

So me and my husband have been trying to conceive since February and still nothing. I’m only 22 and my husband is fixing to be 25 in January. I had the nexplanon in my arm for 3 years and was the deli shot for like 3 years before that. How long before the birth control leaves my system and I can get pregnant. I’m getting so impatient and trying to not get discouraged. 😭😭 what are y’alls thoughts?

Also what are some of the things y’all have tried that has worked for y’all in the past. Thank you in advance 😁
