Worried abt pregnancy

Im currently 7 weeks, and found out i was pregnant at around 4 weeks. I had mild cramps at 5-6 weeks with nausea and back ache and fatigue. However no bleeding. Im a generally very anxious person and i havent seen my gynae as im only seeing them at week 8. The waiting in between is terrible as i dont know whats happening to my body if im overworking myself (my job is quite strenous but i try to be careful now). Any other mummies feel so lost eg. they dont know if baby is still there…?
