Not sure on DPO

Hi! Not sure when i ovulate or have periods because I’ve had a IUD the past few years and when i got it taken out in 2018 i conceived my son the day i got it out! I got one placed after he was born and just got it out on the 10th. Just took one test today to check. Do you see anything? I see a faint pink line. Picture taken 3 minutes after test was taken.

Just wanted second opinions!

Thx!!
