Starting TWW. Anyone else?

I had a stillborn daughter at 38 weeks this passed Nov. This is my second month ttc. (Last month we only tried for like two weeks though). My last and only pregnancy, I got pregnant the first month of ttc so I hope it's quick this time again.

So i get how 40 weeks is 9 months of pregnancy cuz not every month is exactly 4 weeks but im confused how its divided. I got pregnant the beginning of may so the last week of September ends up being 20 weeks which is 5 months (may june july aug sep) but im confused how the last 4 months (october, nov, dec, jan ) also ends up being 20 weeks cuz how does the first 5 months equal 20 weeks and the last 4 months equal 20 weeks cuz im due beginning of february.

im so scared this is an ectopic pregnancy my first appointment isnt until june 1st how can i be sure its not?
