I am within days of being 40 weeks pregnant. I do not want to run to the doctor every time I think my water might have broken. I have been I once because of my wetness and also asked about it once at an appointment. Both times I tested negative on the pH paper. The doctor has told me some women just have a large amount discharge. My question is… Where can I buy pH paper? I would like to be able to test my leaks, so that I don’t over look it when my water actually breaks.
