Help?!

Jessica • Momma of a 3 year old boy, married to my best friend.

I got a positive ovulation test 2+ weeks ago, I’m 3 days late on my period. Just a little cramping but nothing major and all tests have been negative. Took this one about a half hour ago, what is going on? I feel like if I was pregnant I would already have a darker positive

I also have bled a little bit maybe 5 days ago almost like my period started but only bled for maybe 12 hours?! And not enough for a tampon
