I'm not sure how I got pregnant

I'm not sure how I got pregnant. I have PCOS and was told 5years ago I couldn't get pregnant on my own. Eventually I stop trying and simply had fun and didn't worry about it. I got off the pill ever since then. My doctor would prescribe provera every 4months if my period didn't show on it on. My last period was back in November and I went to see my OBGYN on February 10 and it was negative but was not feeling too good in March 15th went to the ER and I was told I was pregnant. As to how I have no clue. Everyone is calling it a miracle baby. On my way now to get my 1st ultra sound done. Wish me luck. Never say never I now say. Have patience and don't focus so much into and simple men joy each other company.
