Date query

[ScMTB]

Hi everyone,

I'm pregnant with my first child, early days and I'm so confused by dates.
My last period started 27th June, my tracking app tells me I'm 4 weeks pregnant but realistically I'm probably only 2.
Period dates are irregular so am I 4 or 2 weeks pregnant? Thanks :)

Pregnancy is dated from the last period rather than the actual conception date.

Above poster is correct. The foetus is 2 weeks old but you are 4 weeks pregnant. That's just the way pregnancy is calculated.

Thanks both :)
