Trying for baby no 2

Naomi
Hi everyone. I have a 2.5 year old girl and we started trying again in February. I came off the pill before Xmas in preparation. Before that I was on the implant for six months but it made me I'll before that I was on the depo after having my daughter. We've had no luck trying yet it did take me 18 months to conceive my daughter. Anyone any advice. I'm 26 and relatively healthy
