8 week round ligament pain? Maybe? 🤷🏻‍♀️

Maybe help ease some anxiety? I'm pretty stressed and trying not to freak out so much from my ultrasound last week.

I'm 41 this is my 4th pregnancy and it's been 15 years since my last one. I've never had any complications or any miscarriages so far 🙏🏼 so I've been really blessed in that way.

I am already worried because at my ultrasound last week, baby was good measuring 7 weeks but had a low heart rate. I go back on thursday for a follow up ultrasound to see if the heartbeat is better. (Please, please, please let it be 😥🙏🏼)

Now last night basically out of nowhere I started getting stabby pains in my lower abdomen like above my pubic bone on my right ride. It's just random. I can be laying down or standing up and it feels like something just pokes me.

Could this be round ligament pains at 8 weeks? I know its a bit early for that but this is my 4th pregnancy and i'm older..so my body is kind of old and tired lol.

I don't have any other cramping, no bleeding or spotting. I peed on a stick and the super dark positive line still popped up (it helps ease some anxiety) Just random stabby twinges 😕

Could this be the start of something bad or just round ligament getting their early stretch on?
