Scared 😩😷

So I’ve been cramping all day. Like not just light cramps they are very tense and are constant. I’ve head a severe headache and felt dizzy every time I stand up. I’m 5 weeks pregnant and my daughter is dealing with influenza B right now so I’m not sure if I’m getting what she has. She’s had it since Monday. I’ve been cold all day and my husband told me I should check my temp. It’s saying 101.3. Idk what to do. I don’t know if I should try to get into the doctors? I’m just freaking out and praying that our lil baby is okay and maybe I’m getting the flu? My husband thinks I should take Tylenol and see if it helps but it’s been going on all day... What should I do? Has anyone else been experiencing these symptoms?
