Okay, I'm a newlywed. Me and my husband haven't tried to have a baby yet, but the symptoms are coming on strong. I also have a thyroid problem which causes me to sometimes have an irregular period or even skip a period completely. I've been havin spasms in my abdomen followed by nausea, mild headaches, I've been so restless at night that I just can't sleep, heartburn, which I've never had a problem with in my entire life, when I lay down and relax, I fell my heart racing as if it's sped up(I'm going through nursing classes so I know your heart rate speeds up during pregnancy) I've even checked it, in the past 3 or 4 weeks my bpms have jumped from my normal of 72 bpm to lie 90 to high 80 bpm. I have nausea in the mornings. And I'm just so fatigued when I actually do get rest that I just don't feel like doing anything. I even take vitamins on a daily basis and excercise normally. With me having a thyroid problem it's hard to tell if I'm pregnant because I skip periods because of that some times too. I really need advice.
