RE: The 2nd (or 3rd, or 4th, etc) time you were pg, did you know it?
With my second I didn't know until they did a blood test because I had some wierd bleeding (thought it was my period - turns out it was implantation bleeding followed by spotting a week later).
This one I didn't have much in the way of symptoms until I was pretty far along, but I had a better idea that I was pg since my period had returned.
Not to be an enabler, but Dollar Tree has HPTs for $1 each so you can test to your heart's content. :-)
