So I have a question as you can see I am 5 days late for my period and I wanted to see what you guys think. The day circled in red is the day I had protected sex with a loose condom and he pulled out. <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">Eve</a> predicts that my ovulation date is on 30 and my period usually 30-31 days apart in which I calculated that if ovulation is 14 days before the next period then it should land on the black circles day. Should I be worried? I had severe cramps that knocked me off my feet on July 11 and have brownish discharge. Now I feel a little nauseous sometimes and feel sick. Could I be pregnant even if I had sex five days or even 10 days before ovulation?
