Glow is completely messing me up

Sarah • 27. Married. My son was born 2/22/16 and his little sister 7/5/17
It says I had my period may 30th and 31st- but I did not track that! My last period was may 7th (beginning my cycle) and I haven't had it since then- so when glow kept predicting my period I kept saying "period is late" but I just checked it and it put down may 30 and 31 and now glow won't let me delete it ugh! And now my ovulation chart is all off 😡
