I'm 17 , Me and my ex boyfriend did things 18th and 19th of December, 2-3 days ago I was taking a shower like I usually do but for some reason I got dizzy , sat on the floor and felt like vomiting , that happened twice , Today My nipples are super sore and It hurts touching them , I have no sign of my period and it's supposed to be here by tomorrow , I always get it early or I'll have signs , what's happening is all new too me , Can I be pregnant? Also My ex did tell me he didn't pull out those days. Those days we're the highest percentage I can get pregnant as well.
