I've recently being having symptoms for the past 2 weeks such as tender breasts/sore nipples, nausea, sometimes I've brought vomit up but not alot and swallowed it by accident. I've been more tired than usual and I had a faint pain in my right side of my lower stomach and around the bottom of my back. I have unprotected sex with my boyfriend everytime and I'm sure we had sex on my ovulation date. Also AF has not turned up today and I'm meant to be due?:/ any advice anyone?
