I had protected sex with my boyfriend on September 7th; used a condom and I didn't break, and he pulled out also. The first day of m last period was August 17th, and my cycle is usually anywhere between 29 and 35 days. Which means I should have gotten my period today, but is not here. I also have felt super lightheaded and dizzy since September 7th and today my breasts felt very slightly tender on the sides, and I have light cramping in my stomach and legs. I've been severely stressed and worried about potentially being pregnant, I haven't stopped worrying since that night actually. So I don't know if that's contributing to this lighthead feeling and some random nausea . I also took two tests and I know it's kinda early but both did come out negative. In just absolutely scared beyond belief
