I Just Put On My Birth Control Patch For The

I just put on my birth control patch for the first time, about an hour ago, maybe an hour and a half. I feel a little weird stomach wise, but I was expecting that. I put the patch on my left buttock, and now the top part of my leg feels like it's about to fall asleep. Is this normal? I heard about people having blood clots on their legs while on the patch and I am kind of freaking out about it. I have very low blood pressure so I thought I was in the clear. Thanks!
