Normal to be clingy?

Dani
Ever since I got pregnant I have been so attached to my boyfriend. I want to be with him all the time. I feel like I'm suffocating him. I try and withdraw but then I miss him. Anyway- I was never like this before. It started in the second trimester. I don't want this to last forever because I am not clingy. Is it just hormones? How many other ladies are obsessed with their partner during pregnancy?
