Another question

Hi everyone ! We are 22 weeks on Saturday! Almost to viability ?our gestational carrier said she can feel him moving a lot and was trying to send us a video today then of course he stopped when she went to do the video! My question is, everything seems okay, no bleeding or spotting even though placenta was low at our 18 week ultrasound, but gestational carrier said she has cramps which she thinka are growing pains because they don’t feel like contractions at all. Same stretching/pulling sensations she has had since day 1. Is this normal? It's hard for me to know since I'm not there. Thank you!
