I was late for my period last month by a few days when it arrived i was on longer than what i normally am. Well according to glow i have just ovulated and me and my husband did have regular intercourse at the time but i have quit smoking but i am in a lot of pain with my boobs to the point i cant really touch them and they do feel a bit swollen but also my gums have been really sort and irritating. I have had a bit of back pain aswell. What do you all think it could be. Is there a chance i could be pregnant but not showing up on a test yet.
