Hello,I had a miscarriage 7 weeks ago, I am trying to become pregnant right now. I love green tee, I drink the one without caffeine I also take several supplements like of course prenatal vitamins, fish oil and something for hair, skin and nails. I also do a lot of sports (elliptical trainer, power walking and running on the treadmill), I do that about 60 to 90mins 5 days a week. I was wondering if too much green tee, the above supplements or the sport can prevent pregnancy or can hurt me if I should be pregnant.
