Did anyone just KNOW that they were pregnant the day after? My boyfriend and I tried for a baby last week. I have had this feeling that I could be pregnant. I woke up the next day and I had mild cramps and literally slept ALL day. Now I just get different feelings in my tummy. I work in a movie theater and on my breaks I usually would grab a little bit of popcorn. I got some today and I couldn’t eat it! I felt so nauseous for hours after. Is it possible that people just know? Or am I overthinking?
