I am on CD10 and on my 3rd day of a fever and sore throat with no end in sight.

My doctor ran a bunch of tests and it was negative for flu, strep throat, bladder infection, pregnancy (duh!), and mono. So she wrote me a script for a Z-pak and said I MUST use birth control (condom) if I take it. She said it would stay in my system for 2 weeks.
I dont want to take it! But, I dont want to get sicker either. I can only miss so much work! My deal with myself would be to start the meds Sunday if I am still sick, but then I dont get to do any baby makin this weekend at this critical time in my cycle.
And, if I dont get my BFP this month, we are talking about avoiding for 2 months to avoid a Dec/Jan birthday (too many in this family already). I dont want to wait!
What should I do?
