Having a cold sucks!!!!!

Akilah
So yesterday morning I started off with a sore throat and by the end of the day I had a sore throat, fever, body aches and a headache. I am 5 weeks and 2 days pregnant today. They say my immune system will be low due to the baby using it. Has anyone else came down with a cold in there first tirmester? 
Please help!!! I really want to kick this cold!
