How to determine how far along you are when you had longer cycles?

Ashlie

So I’m having trouble figuring out how far along I am and when my due date is. I don’t see the doctor till the beginning of February so I’m trying to figure it out myself. My cycles were about 36 days and my lmp was Dec 9 and I got my first positive opk on Dec 30 & 31 so I’m thinking I actually ovulated the 31. So if I go off my lmp I’m due September 15 and if I go off my ovulation date I’m due September 23. Lol on all the pregnancy apps they say I’m either 5 weeks along or 4 I’m so confused 😭😭
