Had sex on my ovulation day with my boyfriend, only in highschool and he used a condom. However condom broke and he came in me and about an hour after went to Cvs looking for plan b but only Aftera was left so I took one.. two days after got scared and took a plan B. Then 2 weeks after the pill and 2 weeks till my expected period I spotted for 2 days. Im now 15 days late and took two negative tests a week after expected period. HELP
