My last period was May 19,2012. I've never missed a period before and I've noticed subtle changes in my body. My nipples are sore, breasts are somewhat tender but extremely swollen, and i've noticed I've gained a few pounds. I've been breaking out on my face more than usual and I've had occasional nausea without vomitting and I've been tired more than usual. How possible is it that i'm pregnant and its not my body freaking out on me? Any feedback would be helpful and greatly appreciated.
