I'm 22 and my fiancé is 25 and we've been talking about trying for a baby on and off for the past year or so.. We are 100% ready now and talked about really given It a go.
For years now though I have had this dout I won't be able to conceive! :( I don't know why? 
I was on the implant for 2 and a bit year had it removed in September . I went onto the pill come off and went back on and now been off the pill for 3 months or longer? I've had a lot of problems in my time with ovarian systs and loop surgery ect .. Maybe a reason why am worried am going to find it hard to conceive. I've done things to help and change my lifestyle by quiting smoking, started the gym and am taken vitamins ect to try and be healthier whilst trying. Me and my partner are sexualy active; he does work away though and i tend to only get to see him a week or so out of a month, so we only manage to have sex when he's back and try then .. But id say properly we've been trying for a few months.
 I've took tests and nothing and it does upset me, It's hard seeing people around me constantly with babies and families; my friends and family and I just can't express enough how much I want to have a family of my own with my amazing fiancé!  Think am just querying how long it has took others to conceive after birth control or people who have been in the same situation as me, or fell like I do? :/ thanks ! 🙏🏽
