Had my circle on the 28th of Nov, had unprotected sex on the 4th of Dec n took postinor 2, had sex on the 13th of Dec n took postinor 2 immediately after, what effect could this have on my menstrual circle and could I be pregnant? Am havin abdominal pains as is common with when am ovulating or about to menstruate, am I pregnant? And recently last night and this morning I've been having blood spottings, but my circle is not due until the 25th if Dec. Could I be pregnant or concerned in any way?
