The rabid, OCD-riddled freak hiding inside of me just NEEDS an answer to this question: At 20 weeks, what month are you in? According to What to Expect, you are in the middle of month 5 which ends after week 22. According to WebMD, you are just beginning month 6 after 20 weeks. I really REALLY would love to be able to think of myself as beginning my 6th month. Is there any consensus out there in the medical world that anyone knows of?
