I think I miiight be pregnant, but I'm not 100% sure yet. I can't afford a test or doctors appointment at the moment, but I looked up ways to test w/o an actual test... it said to collect your urine as if you're peeing in a cup or other. Then leave it set for 3-4 hrs and if there is a white film on top then I'm most likely pregnant, if not then I'm not. How affect is this? Also should I put a lid on the container or not?
