Pregnant or PMSing?

Jade • 28 / husband is 29. Mommy to Abigail Elizabeth 05/30/17 🎀 Claire Victoria 07/01/20 🎀 Eric James 10/14/21 💙 4/08/19 💍👰🏻
So last week I had spotting of only old blood for about five days. Ever since ovulation I have been very nauseated, having hot flashes, and either having trouble sleeping or wanting to sleep all day. My stomach is cramping but it feels just like period cramps. I am late for my period, but I can't tell if it's going to come soon or I'm pregnant. What do you think?
