Preterm labour test!

So

fFN test- preterm labour test. 33 weeks pregnant.

I had to have one of these yesterday due to constant and regular braxton hicks for 6 hours.

I had the test last night but today I am unable to urinate due to the internal pain when I try to go it automatically stops me! I’ve not managed to go today yet due to the pain. It was painful when she carried the swab out.

Has anyone else experienced this? 😩😩
