Hi and welcome to BB. I was on the pill for about 15 years and charted and did pre-conception care for 6 months before TTC. I ovulated the first month and every month after that and conceived on our first attempt. There two great books that I read which are ‘The Natural Way to Better Babies’ and ‘Natural Fertility’ by Francesca Naish. Try not to get too worried this early. We have been TTC baby # 2 for about 10 months and I haven’t been back on the pill. Good luck in your TTC journey.
