question: I ve been trying to concieve and have been prescribed a 7 day course of ampicolix for an infected graze on my foot whilst on vacation. I m mid cycle and 3 days into the course of antibiotics (the cut is wellimproved and swelling on foot has resolved) is this medicine considered safe at the stage of fertilisation should conception occur. I note that there are unproven concerns around cardiovascular effects to the fetus with use of cloxacillin in 1st trimester
