Prenatal vitamins causing breakout, such a thing???

Britni
We've been trying for about 2/3 months. My OB recommended to take prenatal vitamins at least 2 months before trying. I did just that & I've been breaking out since I started taking it. 
Let me give you a brief history of my acne probs. In my mid 20s, I started having acne like a teenager. Prior to that, I had a pimple here & there only.  A doctor told me to try Accutane after trying 1/2 other meds that didn't have good result. I read the side effects of Accutane & was so frightened that I went & got a new dermatologist. She said I just need to take BCP to adjust my hormone and everything will be fine. My skin clears up & I had amazing skin. 
I got off the pills & still had great skin until I started taking the prenatal vitamins prescribed by my OB. I was over dosed (yeah, no joke!) & had a severe allergic reaction bc it contains fish oil; I discovered it one night while I couldn't sleep. I did not pay attention to the label for list of ingredients & trusted my doctor to prescribe the right thing for me since we're TTC.  I'm allergic to fish. After the overdose incident, I started breaking out v badly; primarily my chin/jawline area, chest and upper back. I took folic acid after the incident only per my OB's recommendation. It did not help with the breakout. I found a prenatal vitamins that does not contain fish oil (spring valley prenatal multivitamin/multi mineral w folic acid)  - breakout has not gone away but it helps a little bit. I just switched cleanser; others suggested. I switched facial moisturizer a few months ago too. My chin is bad. I'm picking my blackheads which leads to bleeding & then it turns into black marks. Any tips to help w breaking out??? Thanks!!
