Can anyone see anything?

We’ve been BD every 2 days. My last period was 15th December. I’m usually every 28 to 35 day cycle, I’m currently on day 54. Found out with my daughter when I was 5 days late. Could I have just ovulated late? I’m taking conception vitamins, could they play a part in causing me to be so late? These weren’t taken with FMU
