What theee help

Here’s what my chart looks like...yesterday and today i have had a tiny bit of mild cramping and super light spotting. Very very light and it’s pink. What do you think is happening? 👀

Note: i follow the app according to ovulation but i don’t think its accurate according to my body. I got pregnant with my daughter the day i got done my period back in 2014. I got pregnant with my son 3 days after my period was done in 2016.
