Before I found out I was pregnant, I had been taking Lipo 6 Black (a thermogenic fat burner) for about 2 weeks or so and obviously stopped immediately after I found out I was pregnant. I know it's high in caffein and other stimulants that are harmful to the baby, but could taking them for that period have done any damage? I was about two weeks pregnant when I started taking them and a little less than 4 weeks when I stopped. I am now 6 weeks and have been for a scan and blood test, waiting for the results. Any advice?
