My period came on the 8th of November and was heavy. On the 9th it was gone for about 6 hours, the end of the 9th early 10th it came back although it was very light. the 10th to the 11th it was spotting throughout the day and the 12th it was gone completely again. Now on the 13th it started again with a medium to heavy flow. I did a pregnancy calculator just in case and put in the dates of the first day of my last menstrual cycle. i says that conception would have been on the 22nd of October which was actually the 24th of october when i had sex. my period has never stopped the way it has and i am a little concerned but i feel that it is too early to take a test, but i'm a smoker and a drinker and this is stressing me to have a cig and a apple martini. please help.....what is going on?!?
