Too many "titles" to chose

Hello.. this is my first official post talking about loosing my daughter.. i was two days before becoming 6 months pregnant when i found out my daughter wasnt fully growing, she was a "IGUR" i guess restricted growth because of my placenta, and i can barley remember it because all i remember was being numb and i was numb since Aug. 31st of 2018 until maybe November December? All i kept thinking was what i did wrong? Doctors said it wasnt me it just "happens" i took my vitamins even though i gagged so much from them, i drank water milk etc all the right things. Im trying to conceive now but all i can think about is what if it happens again? I cant go through another heartbreak because loosing my daughter broke my world apart.. i know i am not alone and it probably happens more than i know but is it wrong for me to blame my doctor for not seeing it in time? Im 5'8 and i was barley showing it just looked like a little gut, i was severely nauseous in the beginning and after some research i found that this could be a symptom of an Igur baby.. idk what to think anymore, i know blaming someone isnt going to change anything just wish i had more answers.
