Lost weight then got pregnant??

Has anyone lost weight and ended up getting pregnant? Started adipex - 230 lbs ... goal is to be 150 again. Never had kids, been ttc for #1 for 6 years now. Tried 1 failed <a href="https://glowing.com/glow-fertility-program">IUI</a>. Anyways I've lost 15 lbs and started taking Femenessence Macaharmony to balance hormones as well
