I did a pregnancy test, got a negative and then took fluconazole for thrush (normal dose of 150 mg). 4 days later there was no sign of AF and I got a positive. I knew when I took it that I shouldn't t take it if I was preggers but I thought I wasn't. Taking it in the first trimester in higher doses is associated with birth defects. It appears to be safe if only one dose is taken but there is v little evidence and I am still terrified. I desperately want this baby. Any one taken it at roughy 3-4 weeks? What was the outcome? Thanks in advance x
