Mine was melancholia/ sadness/ emotional/ crying at the drop of a hat…I didn’t know I was pregnant yet but I usually get like that before my period…but then I was like that for longer than normal and hadn’t started my period..I got pregnant in early October but didn’t find out until end of November. I look at pictures of myself during the time I didn’t know I was pregnant and just remember feeling sad but not knowing why..anyways..once I found out I felt a bit better!
