So my bf and I had sex on the 16th my 2nd to last day of ovulation keep in mind this is according to the app so idk if it’s true but anywaysss he came in me. So then now the app is saying I’m one day late should I test? Idk or should I wait? How accurate is this app? My period is also regular and I don’t feel any usual pains like tender breast a week before my period. The only pain is some mild cramps in my abdomen. Thank you :)))
