So the last time I had sex was New Year's <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">Eve</a>/New Years day. Unprotected. I ended up getting on birth control on the 6. So I just got to the colored pill today. I thought my period would've been here by now. I was very stressed yesterday because I thought I was pregnant so I took the test but it was negative and still no period. Could this be the result of stress and the birth control. Btw I have all the symptoms of my period coming  ya know that weird feeling of your vagina pulsing and kinda hurting. And I got cramps too.
