pulling ache/twinge - help worried 😩

I'm 8 weeks pregnant and today I was stood at work helping a customer and I felt a sharp twinge/ache low down in my vagina on my left side (the bit just in between my leg). It only lasted a 2nd and wasn't painful but I can't help worrying. I've had miscarriages in the past but they was a long time ago so don't know if this is one or not 😭😭
