Ok. The app says I am supposed to start my period today but nothing just yet. I did have spotting on & off for about 4 days this past week though. When I got pregnant with my little boy, I was only 17 & had no idea that I was pregnant. I thought I had two periods in one month, but my doctor told me (after the fact of finding out I was pregnant) that the "periods" were just spotting from the egg & sperm connecting & all that fun stuff. Lol! Should I take a pregnancy test to see if I am pregnant?! My husband & I definitely aren't doing anything to prevent it but not really encouraging at this time either.
