Fertile after chemical

Has anyone else had a chemical and then peak super early and end up pregnant? I had a chemical right before Christmas and bled for 3 days. I started having watery cervical mucus on day 9 and took a test day 11 and it was high. Day 12 was a positive so I’m guessing I ovulated yesterday (day 13) which is so early for me. Just wondering if anyone else has had super fast ovulation after a chemical and ended up pregnant?
