33 weeks sharp pain - anyone else?

I'm not worried - as far as my checks / movement etc go I'm all good but would like alittle insight if anyone else is experiencing this?

I personally think it's either my Uterus expanding? Or because of my placenta placement I'm only feeling the low kicks?

Sometimes I get what feels like a sharp knife / electric pain (the blue line shows the pain and it goes downwards), sometimes it's just an "ow" othertimes it catches me off guard and i have to stop and crouch alittle, I have my midwife next friday and it's not regular enough for me to be worried - just catches me off guard 🤷‍♀️
