When would my due date be?

Kayla

I have a short cycle 25-26. My LMP was April 18th. I think I ovulated before the the 1st but I don’t know for sure. Some apps says January 20-21 or January 23rd? I know the days are only a few days off but just curious. What do you think? Nausea started 4 days ago. Just wonder how far along I might be? My first ultrasound isn’t until June 14th & I’m anxious.

I got a positive may 10th
