Hello everyone, I implanted approximately 3/1 got a positive hpt on 3/4 and the next few days the line got lighter and lighter. I called my obgyn to get an appointment went on 3/15 and there was no sign of a baby. She said it was a very early chemical pregnancy. I had light brown light pink spotting between 3/11-3/13. Could that have been my next period after/ now coming towards fertile window? When did your next period come after chemical pregnancy? Sorry for any of your losses! Thanks for the help!!
