How possible🤦🏻‍♀️

How possible is it to be pregnant on the nuvaring? Here’s my story I had a miscarriage and was told to wait 2 weeks. I did not do that stupid I know but he used the pull out method and he’s great at that then at two weeks I had my check up and everything was fine and I got the nuvaring. I put it in and then that night we had sex my doctor said it was fine to and didn’t say anything about needing to wait. So not thinking he didn’t pull out and no protection was used three weeks later I was 4 days late and had a very light threeish day period and then put the ring back in but lately my boobs are tender, I e had cramps and I’m craving food and yesterday I started to spot🤦🏻‍♀️🤦🏻‍♀️
