Braxton Hicks

Alissa • My names Alissa and I'm 18 💕 Just trying to figure out this world.
Can someone tell me what Braxton hicks feel like vs real contractions? I just woke up to the worst pains in my stomach. Almost like I have diarrhea. As I'm sitting here trying to use the bathroom I start to get nauseous and faint. Can someone please tell me if this is normal.
