Sherri • With the help of Glow, now pregnant with my third and final baby! :)
I posted a question about my ovulation test. The problem is is that I asked if it was a positive test without specifying that it was an ovulation test and NOT a pregnancy test!! And when I added in the comment that it's just an ovulation test my pic pops right up! So the whole annonymous question is now known to everyone! : /. So I was wondering if you can delete a comment or prefebly a post so I can re-word it correctly.
