I am 20...I had unprotected sex on the last day of my period which was the 15th of the month...I started my period the 5th of the month..It was the longest period I had lastin 1 week and 2 days..my normal is only 3 to 5 days....I had unprotected sex again on the 20th of the month and the 24th and 25th...all unprotected...It is now the 8th of the next month and I still have not had my period...I am cramping, tender breast, and nausea...however these are also symptoms I get before I start...However my body is not producing the normal signs before my cycle..My vaginal wall is usually a darker pink right before my period, but it is pink and normal right now. I have a lot of discharge...pure white, no smell, thick,but not slightly pinkish as normal...Have anyone had these symptoms and if so what was the result? When I put in my last period day my conception caculator said that if I had sex on the 20th I could be pregnant...as I said earlier I did...could I really be pregnant? My period comes like clockwork,but could an expert tell me if the reason for my late period is a result for having an extremely long period?
