This would be my third child my son is almost 5 and this is the next pregnancy after my still born in May 2019 ... this is my boyfriends first baby and I dont want my anxiety to ruin any happy moments for him. I'm over the moon happy but also scared. If anyone here gone through this please tips on anxiety would help.
