Goodluck for your scan Milly

Your DR is behind the times - tell them to google HCG levels in pregnancy and many reputable sites will agree - they don't double in 48hrs the further along you go. If so the levels would go through the roof

She is worrying you unnecesarily :fuming: . Stress is not good !

Caution must be used in making too much of HCG "numbers". Ultrasound findings after 5-6 weeks of pregnancy are much more predictive of pregnancy outcome than are HCG levels.
As you get further along into pregnancy and the hCG level gets higher, the time it takes to double can increase to about every 96 hours.
I didn't feel any symptoms till about 7weeks and I am pregnant with twins - m/s can start anytime (or not) - depends on your body.
