Hi hollie....Welcome to the forum and congratulations on being pregnant.
Crickey what a situation to be in. The first thing I would say, is calm down.... What you're going through at the moment, is totally normal. Hormones are increasing by the second, and having to work through this on your own is going to weigh down on your emotions. Cry, cry and cry again....Don't feel guilty about crying, just let your body do what it wants to.
Everyone on this forum is really friendly (most of the time - ha ha), so just come and join in. The best way to work out the way you are feeling is to help others that are going through similar situations, and believe me, we are all pretty much experiencing the same ups and downs. Of course personal situations like your husband being in the army isn't the same as other mums to be, but we are all here to pull together.
Welcome, and I hope that things work out for you.
Xx
