My boyfriend and I normally uses condoms but lost the condom twice a month ago the first one we couldn't find thinking it was somewhere in the bedroom. Two days later we lost the condom again and realized it was inside me. I found both inside of me. My period last month was on time but sort of lighter than normal, this month it came on time but very light on the first day the second day I spotted brown and the third day I only spotted when I pee or wipe. What are the chances of me being pregnant?

Unprotected sex can lead to pregnancy. Try a pregnancy test with your first morning urine.
