I know this is a terrible thing to ask, but are you brushing it enough. I remember when I had one of my babies, I'd only get to brush it about every 2nd day in the first month or so and that can make it fall out in the wrong places (like your eggs, lol). I know that pg women have thicker hair though and its a hormonal thing, so after everything begins to return to normal it starts to fall out. I hope it stops soon.
