Okay, so before I found out I was super tired and nauseated on and off. I'm about 4 6/7 weeks and I'm just curious if it's Normal to not feel as bad as I did. I've had slight cramping every now and then but no bleeding. My boobs are still super sensitive, and I can smell everything.. Which my husband makes fun of me for. Anyway, so is it normal for symptoms to come and go? It's kinda freaking me out.
