What can I take for a cold?

I'm only 5dpo so there's no way to tell for certain if I'm pregnant but to be on the safe side I want to avoid anything that may be harmful if I am. Does anyone know what I can take for a cold? I've been sneezing (in the AM only) for two days now today I feel like I have a sore throat. Super sleepy. I just want my bed haha and some medicine. Can I take Advil at least?
