Sorry I never too depo before Or whilst I was pregnant (just making that clear)
I was on depo shot at least two years after my baby girl, started suffering with very painful periods carried on taking the depo shots, while i was pregnant had a scan every other week asked the doc do I have any fibroids as it seems to run in my family he said no, after baby was born had another scan again all clear, went docs complaining about the long periods and the pain that felt like a knife yes no lie like a knife he gave me another scan once again all is clear nothing, period comes again this time I'm telling the doc in no longer wish to continue the depo shots I want a scan to make sure all is clear I've got a fibroid or a Myome so I was told, not happy at all, he also said my uterus was 3 cm or something like this too big. Before anybody decides to get depo shots I would suggest u do yr research specially those who has never had kids don't go by what the docs says do yr own research
It varies from person to person. I had a friend that was using it for about 6mths, and then it took her a year for periods to return. I, on the other hand, was using it for years, came off it expecting not to return to fertility for ages, but got pregnant the next month! Good luck conceiving :)
