Im 6 1/2 weeks pregnant.

Pregnancy is a funny thing, it's something that I wanted so badly and please don't misinterpret I am INCREDIBLY excited. It's just... The last week it has been really hard to feel like myself. I want to feel as happy as I know I am, but lately i just feel really cranky and negative. I think it's just the soul crushing exhaustion, constant slight nausea, tender breasties, bad skin, and pms like mood swings have all culminated into this weird funk. Plus I have the constant "irrational" fears of something bad happening (miscarriage, ectopic). None of my close friends understand, they all tell me I have nothing to worry about, and my sweet husband is so excited. Any tips to help me snap out of the funk? And anyone else feeling this way? I hate to be a complainer, notmally I am so cheery and optimistic....
