Late ovulation...

Hi everyone, this is going to sound like a weird thing to ask but ive never ovulated late before, i normally ovulate around cd 14/16 and like all my other cycles i for a peak on the 17the of feb then it when lower so naturally thought i had ovulated then yesterday my boobs were sore i had mild cramping on one side low down, so did an ovulation test and back up to peak again....now if i left it at 17th the i 'ovulated' af wouldnt have been due for 10 days so im bloody baffled lol has anyone ever had this? I just found it really strange, i know you cant ovulatw twice in a cycle so im not sure which one to believe, one of my apps has stayed that way and the rest have changed so just after any experiences really, was it pregnancy or is it just late ovulation....who knows lol ❤❤
