Could I be pregnant??

So I’ll start by saying I have PCOS and never ovulate. I have never had pms symptoms(sore breast, mood swings, ect) but the past week I have had incredibly sore breast’s and nipples, I’ve been nauseous, super crampy on both sides of my abdomen and have a heavy bloating feel in the middle of my abdomen. My lower back is killing me, I’m constantly hungry(ate 12 count chick fil a with hash browns and yogurt cup) and was hungry an hour later, I was the girl that would eat once a day, and when I say hungry I mean stomach growling hungry. I’m scared to take another test because I took one a few days ago and it was negative, but something has got to be going on. Anyone else have the same symptoms and get the BFP??
