Negative thoughts

Is it normal for preggies n magkaroon ng negative thoughts? Sobrang negative like suicidal thought, escaping from reality ? Almost lagi nko kc naiisip un. Once habang nakaupo bigla nlng natulala then ppasok ung suicida thought. Siguro nga dhil ng problema sa buhay kaya gnun. Napapaisip lng ako na if ndi ako buntis baka i already give in to that idea.
