conceiving after depo is possible!

I was on depo for 6 years. Last shot was June 2016. Period came back last December. First they started out 40 days apart then it was very short like every other week. Then every 23-26 days. I was all over the place. My doctor prescribed me medformin for patients with PCOS. I started taking it about mid May today is June 19, 2017 and I'm 5 weeks pregnant! It is possible! I thought for months that there was something wrong with me We gave up and then I conceived. The world works in mysterious ways! Good luck to all!
