Wait... did I ovulate early?! Irregular periods are confusing AF,

Dev • ⭐️Diagnosed with bicornuate uterus.🤞🏼 Miraculously pregnant with first, due August 2020!❤️

Here’s my chart... almost seems like i ovulated day 13! My cycle runs anywhere from 30-40 days... so I’m thrown for a loop. What do you think??
