This is my second pregnancy. With the first I had morning sickness but it only last up to 10 weeks. I only had back pain the week I went into labor. I never cramped was able to take prenatals. With this one I’m 15 weeks. Nausea comes and goes all the time. Can’t take prenatals or I just throw them up. I tried to eat with them but nothing. I have been cramping and the back pain is killing me. I have no energy to do anything.
