Its normal. First trimester I would sometimes get overwhelmed and just sit in the floor and bawl uncontrollably. For hours. Lol. I couldn't make it stop. It passed after 1sr trimester. I also went back to taking high dosages of vitamin d and a small magnesium supplement too (as I did before pregnancy) because I have deficiencies and having those makes my sadness a lot worse. Don't take anything without doctor approval though.
It happens sometimes when your pregnant. If you start feeling like that all the time you should be sure to tell your doctor.
Im 12 weeks and i started crying on the way to work this morning. Busted out into tears twice. Never happened my first prenancy but this time im emotional. I felt like a teenage girl. I know i looked crazy from an outsiders perspective lol
