So I'm starting to get a little frustrated, having never been through this before I have no idea if it's contractions or not. Over the last week ive had lots of uncomfortable down pressure in lower abdomen and pelvise, like she's pushing down into place. The sensation has always been below my belly button. However in the last 4.5 hours I've been getting uncomfortable tightnings just under my ribs. I had quite a long walk earlier and have felt this maybe 4 or 5 times. I'm not sure if it's my mind imagining it or if it's really happening. Do you just know when it's really starting??
