hi. You may have seen my posts about how I can't understand how far I am along with my pregnancy. On USG they told me I'm 4 weeks past ovulation (15th July the USG took Place) so I can't understand how far along am I.. If I change my dates to 4 weeks, the app Makss that my last period was on 15th June, but it was a date when ovulation occured. My last period was 29th may. If I add two weeks to my app to represent ovulation my baby usg sizes don't match up.. So i get nervous that my baby isn't developing AS it needs to be.. 😢 ahh just so nervous that nothing matches up.. baby's size in the scan was 0,3cm (the yolk sac)
