Hi girls, need some advice! My boyfriend and I normally ALWAYS use a condom as I'm not on the pill. About a week ago 'while I was fertile according to <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">eve</a>' we had unprotected sex however, he did pull out before he ejaculated. 5 days later, I start spotting very light blood. I am not due for a period for another 2 weeks... is this normal?
