Maybe something 🙄

So I have PCOS and irregular periods but normally when I start spotting my period starts within 2 hours after that full blown I have 2 period tracking apps this one and a different one this one I’m supposed to start my period in 2 days the other one says today well long story shorter I had started spotting early today just the littlest amount of pink blood so figured my period was gana start a few hours later I went to the bathroom and it was alittle bit more but still just pink so I waited then I go to use the bathroom again now there’s no blood at all and just this what could it be I’ve had every sign of my period coming cramping a tiny bit nauseous but mostly my boobs and lower back kill and I have a mild headache anyone have any opinions just never had it happen before😏
