Am I pregnant?

Caitlyn • Rainbow baby boy born 8-7-20
My husband and I used the pullout method about a week and a half ago. He's not sure if he pulled out or not because he's not sure if he came. 
About a week later, I got this killer migraine. Nausea,  light sensitivity, fatigue. It lasted more than 12 hours. 
After it subsided, I started noticing other things. I've been having a hard time going number 2. I sleep 12 hours a night. I'm starving! No matter how much I eat, I'm always hungry! I wake up every day with my stomach screaming at me . 
Yesterday, I started spotting a little. Kind of unusual, since my period just starts with no spotting the day before. Glow said it was supposed to start today. It did, but it's different. It's lighter than normal and I barely have any cramps. The cramps I do have are in the front (my usual ones are in my back). 
I don't have to per more frequently, but when I do have to go, it's a lot. 
It's probably just a weird period, but dos anybody else have these sypmtoms and turn out to be pregnant?
