Help 😩

Heven
I just got off my period on the 16th. My cycles are a little longer than normal, but I just started clear blue ovulation tests (the digital ones) and today I got a flashing smiley...is it possible I ovulate this soon after my period even tho my cycles are normally longer than 30 days?? Or is this a fluke! I'm hoping it holds off because my husband doesn't come home till the 24th (in 3 days) 😭Â
