Soooo tired

I’m currently just under 6 weeks and I’m exhausted. This is my 1st pregnancy so I’m always worrying that something is wrong. I haven’t been working so much over the Christmas period but I done a 14 hour shift last weekend and since then I can barely leave my bed. I done a 7 hour shift yesterday and don’t want to leave bed today.

I feel bad as OH is wanting to do something but I just want to stay in my cosy bed. Is this ok?
