Help! Spotting and nervous!

Hey ladies! So I starting spotting tonight a little and I am nervous! I’ve been pregnant before but had a miscarriage at 12 weeks. Last time I knew I was pregnant not even a full two weeks in. I am nervous because I am not on birth control (haven’t been on it in 5 years) and we decided to roll the dice and not pull out (on the days circled in black below). I have been feeling “off” the past couple of days and now I am spotting and I am not supposed to get my period for another 5 days. This app has been completely accurate with predicting my period for over a year and a half now. Is it possible I am spotting because I am pregnant? Any input is appreciated! ❤️❤️❤️❤️❤️❤️❤️❤️❤️
