Flu- 4 Weeks Pregnant

Can having the flu while being 4 weeks pregnant cause any harm? I started my symptoms before getting my BFP but now I’m nervous. And it’s definitely the flu, my daughter brought it home. 🙃I’ve read conflicting things. My symptoms aren’t too bad and when I do get hot, my temp is never more than 100.

Anyone else have the flu this early on?!
