Help calculate my EDD 🧐

My cycles are around 25 days. I believe I ovulated Jan 21st, and i got my first positive test 13dpo on February 3rd. I was due for my cycle February 5th. My positives have continued to darken (thank the lord) and I have had crazy nausea since January 31st. Obviously when I go to my OB, he will give me a EDD, but just for fun, what would you ladies think? It’s crazy to me to get a positive so early (since my cycles are short) and feel this nauseous already when one app says i am 4wk 1 day, and another says I am 3wks 6 days.
