I just found out I am pregnant. I am only about 4 weeks. I am excited and have been reading a lot. I should be having my period this week. I am experiencing cramping similar to period cramps but constant. Is this implantation cramping or normal. I can't get in to my doctor until after the new year but 4 at home pregnancy tests have said I'm preggo. I have had symptoms all month, feel nauseous at night, dizzy spells, heightened smell, super tired and emotional and tender breasts. Anyone else just experience this?
