Sick with The flu- FET transfer Next month

FM • 34 yo- TTC since Oct. 2012. Endometriosis And 9cm Fibroid excised in Oct. 2015.
Just wanted to know if it is okay that I am taking flu medication and my FET transfer will be next month.  Got so sick and I have been taking cold medicine rather than antibiotics..  I was waiting 2 cycles to get all the stims out but now what about these Meds? Please let me know if you have any idea.  Thanks ✨✨✨
