So I had my period on Monday later afternoon.. Didn't have much cramps as I usually do.. But when Af came it was brown.. And Af lasted two days.. Now I am feeling sick and have the worst mood swings ever!! A little nausea.. Boobs are a little tinder... And super tired and everyone said I looked tired. Having little cramps too... I mean I got like 8 hours of sleep.. Took a home test and came out nagitive... Help!
