TTC our first after July miscarriage

Hi all. According to my OPK, I would have ovulated last Saturday (6 days ago). My doctor has stared me on a supplement called Pregnitude. I travel daily for my job and have been taking this for about two weeks. Today, I am so nauseated I can hardly stand it. Are my hormones just trying to regulate or does anyone have any experience with this supplement? Driving around in the car is hard when I'm feeling this bad🤢
