Last month I got my period on August 25th and it lasted a few days, my period is always on time or a few days early, this is the first time it has ever been late. The thing is I had unprotected sex (but im on BC) on around August 20th-21st. Is there still a possibility that I am pregnant or is my period just delayed? My period was suppose to be due by the 25th and my cycle normally ranges from 28-30 days. Also, last month (August) I got my period twice, but both periods were different than normal. Please help! Not sure if this matters, but last time I was late I found out I was pregnant with my son, 10 years ago.
