stretching feeling? tmi warning

morganoo

So today I'm 37 weeks and 5 days with my first baby. I've been getting a weird kind of painful feeling in my lady parts and in my lower abdomen. it feels like stretching. I've gotten it a few times but now it keeps coming and going every few minutes and hurts a bit more than normal. I would say it's like period cramps but kind of different. But it actually feels like my vagina is stretching and was just wondering if maybe this is early labour signs?
