Hello everyone!

so as you know I got.my BFP at the weekend. before that my periods were off....like beyond off.

I ovulated on the 9th of July and am now pregnant...and trying to guesstimate how far along I am! the apps have put it at 4 weeks but kept asking date of my last period. I'm not to good at working this stuff out. does it sound right to you? DD at the min of 1st April!
