Cramping after orgasam

So am not due af for another 4-6 days give or take

and last night when me and my OH done the deed I had really intense cramps after an orgasam, I’ve never had this before other than the last time I was pregnant which ended in ectopic.

Symptoms have been all over the place

- vivid dreams

- hot flashes

- dizziness

- loss of appetite

- sore boobs and some pain under the armpit

- tired all the time

- some cramping

- thick cm

- emotional as hell

- and serious mood swings

Anyone else have cramps after an orgasam and go on to be pregnant I’ve read up online that it’s been a first sign for a lot of people just to scared to test as it’s been 2 years since our last loss just so nervous
