So my boyfriend and I have decided to start trying for our first child. Currently, I’m 16 days past ovulation and my period is about two or three days late. I never ever miss periods and I haven’t done anything different so I’m not sure what’s going on. I’ve taken pregnancy tests and they have all come up negative 😪 I do have quite a few symptoms but it could all just be in my head. Anyone here having the same problem?
