I have been getting tightening on my stomach but not painful for months . Now getting a bit stronger. I am 36 weeks and 4 days pregnant. When I went for 36 weeks baby was just on brim of the pelvic. She wasn't going to put as engaged at all at I have 3 baby's as may change. As it does once u have more than 1 baby. With my 3rd they told me for engaged then I wasn't .
