Moody like a B

My wife and I did a insemination on the 1st, since Sunday morning have have been moody like no other! I get angry towards her over things as simple as Ice cream 😬 After I eat almost anything I feel pressure like my stomach is going to pop and I get these crazy pains, like cramps not not like cramps and not from the pressure either and I’ve been so lazy/tired.

My period should be in about 9 days and we are 8 days past the insemination. I’m scared to test because I don’t want to get myself down, but should I test?

Could this be a good sign? Or could it be a weird period month?
