Hi, my latest menstruation period is on 13th of June and ended on 15th of June, I have petting naked but no ejaculation on 20th of June and started spot light pink spotting on 26th, red spotting on 27th and 28th, and brown spotting on 29th and 30th of June, and again light pink spotting on 1st of July, my cyle is either 30 or 31 days, those spotting occur during ovulation time as I read on many websites, could it be pregnancy or not?
