Hi all, im currently 7 and a half weeks pregnant. Been pretty nauseous and tired and boobs have been so sore but for the past two days iv hardly had any nausea and my boobs arent that bad. My minds in overdrive and now i think somethings wrong? Iv been getting the odd mild cramp on and off. Am i just being stupid? Had an early scan at 6 weeks which showed a strong heartbeat but im also aware things can change.
