Worried about pregnancy

monty

I am 32 yr old we plan for baby for 1 yr this is my 1st pregnancy no any other complication previously .according to LMP it’s 7 wk 4 dy and according to USG 6wk 1dy

In USG cardiac activity seen nd it’s 100 beats/min

Gynec said tht it’s not gud wait for 4-5 days thn repeat USG if it is not increased heart beat more than 100 it is possibly complicated pregnancy

So now we worried about tht
