My boyfriend and I had sex the 26th,27th and 28th when we were out of town. It’s normal for me for be 3 or 4 days late starting but not this late. Pregnancy tests are negative but I figured if fertilization happened one of those days I’d only be about 2 weeks if I am. I’ve only had clear discharge, no cramping, been peeing on myself when I sneeze more but I do have a son via c section already so it happens sometimes but hasn’t happened this frequent in a while. I do feel forgetful, and have like a sensation like I’m a bit dizzy like I kinda want to puke but not gagging or anything if that makes sense and I’ve been super tired. Is it possible to be pregnant? And it not show up on tests just yet?
