confused?

alli • Mommy to a beautiful baby girl 💕🙌
So i just found out i was pregnant two days ago. I made a drs. apointment but its not for a few days. glow says im exactly 4 weeks today but i dont see how its possible because my most fertile day on glow fertility which helped me get pregnant was only 15 days ago, and my period was 31 days ago. i put that info in here and somehow says that im 4 weeks i just dont understand. but if i was less then 4 weeks i also dont know how it would show up on a test that i took 3 days before i was supposed to get my period and i took it at night after i peed like 10 times that day. Sorry if this makes no sense but what do u guys think?
