Okay ladies so I’m over a week late on my period. We used a condom the one time we had sex this month right around my usually ovulation. I took a test a few days after i missed my period. (I didn’t track this month so i could be off by a few days) my cycles sometimes are a few days longer than others. I took a test a few days later still negative. I cant think of any other reason why it would be late. Im going to test again later tonight after work. However, is it possible to get a negative even if your period is late and to get a positive later on.
