So this happened

My last period was the 6th of March so I was waiting on Aprils already bought my pads pills and ice cream lol my period usually starts the same day or a little before or after but I forgot all about it . And before I knew it I was 9 days late but 4 days ago I started cramping and I always cramp a week before my period . So I knew I was finna start but yesterday I was like well I’m 8 days late imma just test just so I know I’m not pregnant. Well I tested alright and this happened. But I do want to know when does the cramping stop they aren’t like I can’t walk horribly bad but they are discomfortable cramps 😩
