I'm 15 weeks pregnant. This last week I was sick with a sinus infection. I also work night shift so my body has been very fatigued. My question is a few days ago I started having tightness all over my abdomen. Not just my lower, from top to bottom tightness. It's very uncomfortable. I would describe it feeling like Braxton hicks. I'm not having sharp pains and no bleeding so I've been trying to hold off until my doctors appt on Thursday. Is this normal or has anyone experienced this? I don't remember doing this with my first.
