Me and my boyfriend have been having unprotected sex for 5 months now. I haven't gotten pregnant and that's not a bad thing but this past week my nipples and the area around my nipples have gotten really sore and still are. These past couple days my stomach has been hurting and I threw up a little in my mouth. The area where I normally get bloated is slightly bloated. I use the <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">period tracker</a> on this app and normally it's wrong so I should've had my period a little bit ago but I haven't. It says I'm due on thu for it but it's weird how it could be right this time. I'm scared that I'm pregnant. I've read about stuff online but the symptoms I'm having can als be signs of my period. I don't really know what to do.
