First pregnancy, All of a sudden cramps switched sides

I’m sure I’m just paranoid, but I’ve had cramps my entire pregnancy. (Only 6 weeks along). They’ve always been intermittent and on my left side. They feel like easy period cramps, nothing crazy, which is normal. The last two days, they have switched sides and have become more intense. More like a stab than an ache. They go away after a few seconds but it’s still pretty scary. My first doctor appt isn’t until the 12th. Should I go into the ER? Urgent care? Ugh, this is scary! Thanks in advance
