What Causes Missed Period, Lower Pelvic Cramps And Itchy Rash On Lower Back?

Rashes and itchiness at side of stomach, the the side of lower back, arm towards wrist area, and high butt crack. I always eat all over the place so I couldn t determine anything from that, but i have noticed a slight difference in my choice of foods. I ve had a few cramps in lower right pelvic region. My menstrual cycle has not come on for nearly three months. I ve been a good bit emotional lately. I ve noticed I ve been a good bit restless at night yet can still have energy in the mornings. I ve just begun having small sharp shooting pains in my lower back area. My stomach has looked like I was carrying for years now. My bf asked if I was pregnant early one morning because he had been so tired lately, he didn t know that I was having symptoms of being pregnant. I don t know if I m pregnant or what. I ve had false alarms before which is why I ve put off really finding out, but there are way more symptoms this time around.
