Totally different!
DD1 i had no symptoms at all didnt know i was pregnant till about 6weeks when i clicked that i hadnt had my period! no ms or anything
DD2 no symptoms leading up to BFP, just my usual pre period type ones, MS from week 6 to 16
D?- lots of pre pregnancy symptoms, cramping, moodyness, implatation pain, tingly nipples ect, and so far not one hint of MS!
