Sick and no meds!

Lena • I`m 28, 💍for almost 5 years and TTC for almost 4 years. Taking it 1 day at a time.
So this is the 2nd month in a row that I have gotten a head cold right around O time. It sucks because I can't take cold medicine (dries up CM). Anyone have ways to get rid of a cold without messing up their cycle? Anyway get sick during O time?
