First pregnancy I Never got tired except For an occasional nap and At night time. This pregnancy OMG! I'm always tired, sleep everyday All day, stay awake For a few hours When bf Gets off work and Then back to sleep At night. But I have a rough time sleeping At night Which Is Why I think I sleep So much during The day. It's completely normal But If your extremely tired and lack energy to ever do anything, Plus get nauseous, headaches, Or dizzy Or anything like That ask your doctor about possibly having low iron. Because once my sleepiness started being sleepiness Plus throwing up everything and having very bad aches n pains every day and wanting to get up and cook Or clean But not having The energy to do It I went to The e.r and found out I was extremely anemic.
Yes i would fall asleep even when people were around :)
