You should call your doctor and ask. But also keep taking those tests to find out if you are pregnant. Good luck!!!

Goodness me gillian, try really hard to avoid antibiotics if at all possible, not only are they a trigger for thrush and yeast infections but the more you use them the more they will lose their effect when you really need them the most. I don't know if antibiotics can delay your period or cause a bladder infection, but worrying always seems to delay my period. Get some ural satchets for the bladder infection from your local chemist so that the infection doesn't go up to your kidneys and get really painful.

Good luck gillian
