I am currently 12 weeks and about to go onto 13 weeks. I had a scan at 12w 4 days and I had a comment from someone about it that from the nub theory its a boy.. I have severe birth trauma and the minute I heard its a boy its triggered a lot of pain and anxiety. I have two boys and I don't know if its because I gave birth to a boy last birth that's the reason why its set me off so bad. From the minute I found out I was pregnant I have felt its a girl. so I don't know if that's how I been trying to get through this PTSD in the first place. I am currently seeing a perinatal psychologist and i do have another appointment in two weeks. Should I even take notice of this nub theory? maybe its the need for a girl I'm longing for which gets the mum guilt going even though i am so happy with my two boys..
