Vvvfl!! I don't know when my due date would be?

I think this is it!! My last AF was June 13th and today I have taken now 4 tests and all of them have a faint line! I took one with fmu and the other ones each time I had to pee with no hold! We found out on Thanksgiving we where pregnant but we lost that baby and then Christmas we found out we where pregnant again but again another miscarriage and today July 4th we found out we are pregnant! Here are a few pictures and also my chart as I definitely had ovulation early!! Praying this one will be our rainbow 🌈 👶🏻 baby. I have 4 kids from ex and his first baby from his ex passed away 20 years ago at 22 weeks gestation We have had multiple miscarriages and we just pray that this little one will stay out for 9 months! Now I'm just trying to figure out when would my due date be?!
