Is there any way to figure out due date?!

Jessica • Mom of 2 boys, 1 girl🧒🏼👦🏼👦🏼26 years young. Engaged💝💍

Please read. So I haven’t had a period since January 15. Started trying for baby February 11. Had sex every 2-4 days. Last time we had sex was March 17. I have no idea when I would be expecting my next period and no idea when I ovulated or conceived. Is there any way I can figure out due date? This is my most recent pregnancy test taken today.

Line is still somewhat light so I can’t be more than 5 weeks. Ugh this is so confusing! Don’t see my doctor til April 17.
