Over the past week I've been having pregnancy like symptoms , liking food I normally hate , fatigue , insomnia , pinprick/mild period like cramps that come and go, tender breast (again this comes in spurts it's not constantly sore) etc .all day yesterday I had to go number 2 after every sip of water it felt like .  Last night I started getting chills and extreme nausea and it's been happening again today and it comes in waves . I get a mild rise in body temperature , it goes from 37.0-37.5 nothing crazy so if I am fevered it's mild but I'm having chills and feel extremely nauseas on and off but I haven't thrown up . Does the nausea and chills sound more like the flu coming on or should I chart it as a possible symptom ? I'm trying to keep track of everything .
