Calculating Due Date

Steph

My period is super irregular so I’m not exactly sure when my due date is. All I know is that October 13-16 I was taking ovulation tests that showed I was super fertile.

I took a pregnancy test Thursday Nov 14 and there was a very faint line and a negative digital test. Sunday, the 17th I took the same test and the line was dark. I also got a positive digital test.

My first appointment is not until Dec 11 so just wanted a ballpark of a due date. TIA!
