I'm going to try to make this as short as possible.. me & my boyfriend had sex on Oct. 6th, then on Oct. 10th, I got my period so I didn't think I was pregnant, but my period was two days late this month, I've been having some cramps, I'm extremely hungry, frequent headaches, & some nausea, but when I started my period, it was pretty light, which is not normal for me, I'm not sure if it's possible I am spotting or if it's my regular period. Help?
