Hello I am really hoping someone can help. So I have a 6 month old child & have been breastfeeding so not had a period yet. Myself and OH had unprotected sex 2 weeks ago. The other day I got the most horrendous pain in my left hand side radiating around to my back. Could this be implantation? It was exactly 2 weeks after the unprotected sex. I am also having pain when baby is latching on. I have had some discharge aswel. Have took a test which is negative. Could I be pregnant???
