What week is the beginning of the 3rd Trimester?

Question

Just curious? This app says 26 weeks, another app says 27 and I’ve seen charts that say 28. 
Why?

Answer

Its the 28th week
13+13=26 
BUT!!! its only a chemical pregnancy for the first two weeks, so add on an extra two weeks to 26 and Ta-Da!!! 28 weeks 😛
