My last menstrual period started on the 2 of January and ended on the 8 of January. Guy A had sex with me and finished on the 11 and 16. We also had sex on the 21 and 25 but he didn't finish
Guy B I had sex with February 7 but he didn't finish. I am currently 19 weeks pregnant and my due date is October 19.
In rough workings I would say guy A because working back 19 weeks takes it to Jan 15th an working forward from the start of your period you would of been fertile around the 16th
But wouldn’t I be further along?
Going back 19 weeks takes you to the 15th Jan, early scans aren't necessarily that accurate on due dates.
