Pregnancy

Hi, I'm trying to conceive and been working on it. Last week i experience breast & nipple pain, nauseous, slight stomach pinching/cramp, backache and tiredness. But since last Saturday ... the feeling for it seems like done i do not feel nauseous & stomach cramp, breast wasn't as painful as previously. And today I start to feel all these symptoms again... is it normal? Do u all experience these on off symptoms during 1-2week of pregnancy?
