Has anyone taken too many vitamins and everything been okay?

I feel awful, completely stressed, and not sure what to think. I’m always really low in certain Vitamins and when I found out I was pregnant approx just over 2 weeks ago I started taking twice the amount. I’d take the dose when I woke up and when I went to bed. I should of asked my doctor but I don’t know what I was thinking. I just recently saw that taking too many can cause potential defects and I’m so scared I didn’t take any last night or today because I’m so worried now. I’ve lost a couple of pregnancy’s before one due to low progesterone and saw that certain vitamin deficiencies could contribute to low progesterone so that’s when I started. Maximum 2 weeks maybe 1 1/2. Im so lost but I don’t see my doc until the 27th.
