My period started Sunday July 1st and ended last Wednesday, July 4th and my boyfriend came to town and we had a lot of unprotected sex June 6th, 7th, and 8th. And i mean a lot!!! Like we had unprotected sex about 3-4 times each day. According to my <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">period tracker</a> I just became fertile. And it’s too late to take plan b. Is it possible I could be pregnant!?
