K so I had my period the first week of July and it ended some where between the 7-8. I had unprotected sex on the 9th and he pulled out but I was still scared about precum so I took a Take Action pill the morning after and it wasnt even 24 hours yet. Then a week later I had a light bleeding (dark red) that lasted about 3-4 days, what did that mean? My period is always on time and usually comes the last week of any month leading into the first. Now its the first week of August and I still havent got my period, im starting to freak out a little. Im having cramps and mood swings as if it were comming but still no period! Is this normal? How long will my period be late? Someone give me some sainity because im only 18 and in no place to raise a child and im scared to death.
