Snoopy- I say this in the most gentle and loving way possible- it really isn't a case of 'should' be feeling cramps and boobs 'should' be hurting more. I know I'm going to be just as neurotic if I get pg again, but from my currently objective not-pregnant perspective, analysing how your body feels probably won't help you, it will just torture you.
I had two pregnancies. One perfect normal one resulting in my beautiful dd. One identical one which ended at 11 weeks. With both pregnancies, my symptoms disappeared at 9 weeks. With one, it meant that my healthy placenta was talking over. With the other, it meant the pregnancy was ending. So I have learned that symptoms don't actually mean anything.
And no you shouldn't be feeling cramps yet. It's really too early to fell anything. If you were, it would probably be a sign that everything is fine. That you're not is probably also a sign that everything is fine.
Today you are pregnant. Try to just focus on that. Nothing you do will make any difference. Either this is a strong one or it isn't. Most likely it is. I know it's easier said than done, but try not to panic at every symptom or lack of symptom because it won't help you. Every pregnancy is different.
Today you are pregnant and that is so wonderful. Try and hold on to the utter joy. You have a teeny tiny bean growing in your belly. Right now.
