Emotional

For the last few weeks i have been ever so attached to my husband.. needing attention a lot! At first i thought it was my husband just not showing me as much affection but hes saying its me that seems to be reading too much into it and its me thats been a bit more clingy. I seems to have been like this since he went on my brother in laws stag weekend a few weeks ago n he was away for 2 days so i missed him a lot! He has another weekend in june coming up but i dont want him to go as i will be 32 weeks and already feeling down about myself. Its almost like i need constant reassurance from him.. is this normal and will it go away?! Im scared im turning into a crazy pregnant lady! :(
