I had a difficult time sleeping through the night and could not get comfortable. I kept feeling a lot of pressure very low in my pelvis and by early morning I had some "cramping" (more so on my right side,) as well as lower back pain every time I got up to use the bathroom. I know low back pain is common but I haven't had much of an issue with it since I had a large cyst removed at 15 weeks. I am now 30+4. I'm super paranoid about preterm labor. I was 2 months early and so was my sister. My husband was also 2 months early. Should I be worried?
