Alright, this is going to sound ridiculous, but I feel pregnant. Wednesday morning, I felt a light twinge. Yesterday, I had a headache, cramping in my lower back, and was exhausted all day. Today I'm so tired I could sleep standing up, my back is KILLING me, my head has a constant dull ache and I have had a sour metallic taste in my mouth all day. I have felt a slight pressure or "heaviness" to my uterus since this morning. The kind of feeling you get when you think your period will start an second. I felt the exact same way when I was pregnant with my daughter. I'm active duty Navy and am currently on 24 hour duty, so I wont be able to take a pregnancy test until tomorrow and it's killing me. What do you guys think?
