Bloated?! Advice please?!

Fiona
Just wondered if anyone could shed some light here please?
We made an attempt on the day of ovulation, last Thursday. I'm now technically 7 days away from AF being due, I have had light cramping to really strong painful cramps for the last 3 days or so. (Usually I only get light cramps while I'm on)
This afternoon I have noticed my lower abdomen is really bloated, stuck out. Which is not usual at all for me. I'm not constipated, it's not high enough to be a food baby!!
I've also been a moody, irritable cow for the past few days..
Has anyone had anything similar?! I know it's probably too early to test, but we do have first response if necessary.. Should we test? Or can anyone explain what this could be??
Thanks in advance!!! ☺️
