Birth control effects on pregnancy, any positive stories?

I have been on BC for 9 years and stopped taking it 8 months ago. We started TTC in February and ended up pregnant in April. However that ended up in a missed miscarriage. I am TTC again but feel a little deflated as I have seen a lot of posts where women who have been on BC for aslong as I have, have been struggling to conceive and if they do conceive a lot of people have said it ends in a miscarriage. Is there any positive pregnancy success stories for people that have been in BC for such a long time before TTC? And how long did it take for you to conceive?
