Hi well my last period supposed to be on june 5th, I am not exactly. Well on june 3rd I had some spots not red as blood the the two days after those spots were like pink another like yellow/brown. I'm confuse if that really was a period or what?

Last week I made a Prego test cause I know when is an implantation a few bleeding or spots can occur but the test was negative. Now Glow says tomorrow start my fertil days

I'm a little confused, we used condoms but a couple times we don't. We are not looking for a baby but if happens is welcome.

Some help, some advice in what's could going on ?
