Hello my last period was July 20th annd my cycle usually is 29-30 days causing my ovulation dates to be between August 3rd-5th according to the ovulation calender on my phone. We had sex on August 2nd and 3rd. On August 9th I noticed some spotting while I wipped after unrination. It was on and off and only for that day. My period is not due until the 20th of this month so I can not take a hpt yet. My husband do not use protection, I am not on the pill and he pulls out.. do you think I could be pregnant?
