What’s this in my urine? My monthly was suppose to come on the 9th but it still hasn’t showed up. I had sex with my boyfriend last month on the 27th during my fertile window and on the 3rd. He came inside me on both of dates! Yesterday I bought two first response tests and both came out negative. I think I tested early! My period is never late and it’s on time! My monthly cycles are regular and my last period was January 12th which lasted only for five days.
