TTC and i am sick. What to do.

Samantha • TTC my rainbow baby. Lost my Zackery 3 years ago. Infertility problems, hoping GLOW helps.
I am at my 2 week wait, my period is supposed to come in 3 days. I now have a cold (cough, sneeze, congestion, sore throat, mucus). I am trying not to take any meds in case I am pregnant. What can I do? I have been drinking a lot of hot tea, but it only works for a little bit. My throat is getting so sore. What can I do for this if I am pregnant?
