Ya sorry week 13 is the first day of the 3rd month. Week 18 is the first week of the 4th month. Wrote it wrong.
She wanted to know what week starts the 3rd month nit what month ends it
Yes week at the end of 13 weeks you are 3 months pregnant.
Week 13 is technically the last day of your third month. Week 1 is the first day of your fourth month. I'm 3 month and 5 days. 13 weeks and 5 days. :)
Oh okak, that's the end of the third month?
