How I got pregnant?!

I got off birth control 5yrs ago and my cycles were always off and very painful. I was diagnosed with PCOS 6yrs ago. I was in a bad accident and gained weight around that time I had failed 6 cycles of clomid and femera. Last year at this time I was at the highest weight I’ve ever been. I was super unhealthy and PCOS symptoms were through the roof. I got on Metformin. I started Keto last May and worked on my diet, I went to eating organic foods when possible, I use organic products (hair care, pads, tampons, laundry, lotion, face wash, cleaning supplies) I knew all the chemicals I was putting in my body was harming me. I started to work out again. Started to take vitamins. I was on Vit D, omega, prenatales, and a month before I got pregnant I took vitamins called conception (from amazon). We started trying the beginning of this year after I lost 40lbs. We did a round of Femera, trigger shot, and BD

with preseed and here I am 7 weeks pregnant!
