One app says my period was supposed to start on Sunday, making me 3 days late today. Glow says I'm supposed to start today. Last month both apps were on the same schedule and I started that day. So I'm not sure what happened. But I took a test a few days ago at night and it said no. I should have used fmu but I'm too impatient haha. Well I get waves of nausea throughout the day and sometimes after I eat. I'm tired earlier but then I can't sleep. I end up staying up until about 4am. I have bumps around my left nipple that I've never had before, Google says it's Montgomery tubercles that it's usually a first sign of pregnancy. My boobs have been sore on and off. I've been bloated and a tiny bit crampy on and off. Sometimes I think I'm pregnant other times I just think I'm crazy! Anyone experience this and end up pregnant? I'm trying to wait a few more days before taking another test.
