so i am confused. i was suppose to get my period jan. 11th, 2010. it was 6 days late, (i got it the 16th) and it was more like spotting and was over the 18th. my period lasts 5 days, not 2. i thought i was pregnant, but apparently i was not. so this whole time i have been peeing on sticks and being really confused about a 2 day period with no pregnancy. so i am wondering, is it likely that i will get it the 16th next month??? and how do i recalculate my ovulation tracking
