I've missed my period by nearly 3months now, taken 2 pregnancy tests but they've both come back as negative? The only symptoms I've had is tiredness (which I put down to work) and white discharge. I never miss a period, not this late anyway, so what should I do?? I went to the doctor but they told me to go and come back once I'd taken another test ( Which came back negative) so then I decided to get some advice over the phone from a health care advisor and they told me to go back to the doctor and get it all checked out?! Am I pregnant or paranoid?
