35 weeks. Having intense pains like period cramps in my lower abdomen coming in waves but not regular. Tried timing but never goes completely so not sure when to start or Finnish! I had ligament issues which felt similar at 22 weeks and spent 2 days in hospital. Now I am unsure if this is early labour or my ligaments returning. Can't sleep and supposedly at work in morning. This is my third but first two felt quite different. Been a while too so can't really remember! Help?
