While I might have occasional twinges of queasiness earlier I don't get morning sickness that is enough to notice before 8 weeks. Third pregnancy now and its been the same with all three...morning sickness from about 8-14 weeks or a little longer.
I kept thinking I had the flu about a week before AF was due. I had NO clue I was pregnant - didn't think it was even possible (we were preventing). After I was 3 days late and still sick hubby insisted I take a test (i was sure it would be negative).... sure enough!!
