I had unprotected sex on the last day of my period and took a morning after pill a few hours later as precaution. On the expected day of ovulation (based on my mobile period tracker) I had sex but with a condom. We checked and there was no break. I'm supposed to have me period 2 days ago but it didn't come. Instead I started spotting today. This is my first time spotting and I did not spot previous times I took the morning after pill. Should I be worried about pregnancy?
