Having symptoms..

My boobs are sore, I'm peeing more often, I have strong cravings and I'm
Hungry more often and never really feel full, and I'm extremely tired and sleep a lot now. I am on the patch but could I be pregnant? Me and my boyfriend had A LOT of sex at least 7 times a couple weeks ago and he came inside of me every time. I'm okay if I am pregnant and my period isn't due till next week. Could I be pregnant? 
Update:I'm now having light stomach cramps like not as strong as period cramps but I notice them. And I have a light pink discharge.
