Help!

B • Mommy of one 💜
I have had ewcm for the last 4 days what could cause it? I've never noticed it with ovulation before and my cycles are so irregular so I don't know if I'm actually ovulating or not! I am on amoxicillin and I also use generic afrin for my cold I have ( I don't know if that could effect it) my boobs feel slightly tender too.. Could this be ovulation?
