Am I pregnant?

Shelby • Just think happy thoughts!
I had sex the four days leading up to my fertiliy window (at least according to Glow) we didn't use protection. But he told me because he is on the blood thinner Coumadin, he can't have kids (I looked it up and .01% out of 100 had a slight problem with sperm count) and right now my period is in two days but this whole week I have had sore nipples, heavy breasts, smoking makes me throw up, I have nausea, lower back pain,  neck pain and cramps, I can't sleep, smell food that is no where around, and am just so emotional. My friend said it could just be my period. But I have never had any cramping, sore breast, bloating or any other pains and ails that come with that time of month. Usually all I get is achne the week leading up to it, but this time I have no achen but everything else.
