Just curious πŸ™‰

Is my fertile window on glow accurate? Suspecting I'm pregnant. But I don't know yet, could it be that I ovulated later than what glow says and I'm just not enough DPO for it to show up yet? Supposed to get my period yesterday and have weird sharp like pains in my pelvis. Could be PMS but really feels different. Also (tmi) but I normally have a problem 'going #2' but I've been going so much😩 just some opinions needed ☺️ thanks girls!!!!πŸ’“
