Ovulation date correct

So I’m tracking my bbt and for the past 3 months I have had my period on exactly 28 days. In March I had a confirmed ovulation on my bbt on cycle day 16! For April It looks like I had confirmed ovulation on cycle day 14 but my cycle was only 25 days!!!

My question is: I thought your period comes 14 days after your ovulation. So if I ovulate on day 16 I would expect my period on day 30 because it’s 14 days after day 16???
