Uy, this sounds worrying talaga, please see your OB or go to the ER right away, ha? Bleeding like that, especially with a gap and then it comes back, really needs a proper check-up and ultrasound para malaman kung ano talaga ang nangyari. A few of us moms have been through spotting scares, and honestly, the waiting is the hardest part, but a doctor will give you peace of mind or proper care agad. Don't worry too much in the meantime, but please don't wait on this one. Take care of yourself, and keep us posted when you can.
