Whats going on with me

li

Okay ladies, so for the past two weeks I’ve had really tender breasts. This started happening around 4/2/18. And having pms tender breast a few days before my af is normal for me, but what’s strange is that it was a lot worse than normal and lasted a lot longer than normal. My af showed up 4/13/18 and only lasted four days (so till 4/16/18) and I still have tender breast and nausea. I dont know if it’s just my body going through a phase, or if this isn’t normal, or if it was just a (i dont know what to really call it) false af and I could be pregnant. Any advice or any of you ladies go through this?
