Coming off cerazette

Hwy ladies, me and my husband have decided to try for our 1st baby. I came off cerazette on the 2nd of this month and was already spotting ( I normally have a period on cerazette) anyway this period was so much heavier with more intense pain and lasted dead on 5 days. Would you class this as a period or a withdrawal bleed? Glow suggests I will be ovalating Sunday, Will I ovulate this month? Thank you 💜
