hey. my period lasts for about 3-4 days. and I had sex the last day of my period and we had a mishap with the condom and we stopped. I took the morning after the ( Norlevo ) both at the same time 16 hours later. so 6 days after I noticed some spotting amd I've had cramps and headaches. even back pains.. can the spotting be sign of pregnancy or the pill worked?
