Can I have some advice please ladies on tummy pain..?

So I am 35 weeks tomorrow and I've been experiencing tummy cramps (almost like period pain) for the last couple of days, I noticed it the most yesterday. My tummy doesn't tighten when it happens and there is no pattern.

It happens when I stand up or walk around AFTER being sitting/laying down and then lasts probably another 10 minutes once I sit back down again.

It does occur when I'm out and about too. Not just when I stand but that's when I notice it the most. It generally doesn't occur when I'm sitting/laying.

If I have to get checked out obvs I will but the hospital is so far away and such a long wait, I don't want to go if this is normal.

Has anyone else experienced this?

I'll appreciate any advice or stories if anyone else has had the same.

I've posted this anon as some people are so rude and judgemental on here so I won't be commenting back so thank you In advance xx
