I'm assuming I'm very irregular

Kennedy • Married to my soulmate since 7.4.2020!💍💞 We have a 4 year old son, who took a year and a half to conceive! We are expecting baby girl March 11th 2021 after 2 1/2 years of ttc with fertility treatments 💖
These are my cycle lengths .. the ones that are circled is when I was on nuvaring so that's why they're normal length. It's a surprise to me how I got pregnant
