History noted. Please stop worrying. The stress
at times may lead to miscariage, but not always. Stress have lead to many mis cariages, but the exact relationship was not established till now. So think positive, become calm and cool as soon as you can.The positive drive will help you to continue this pregnancy
and prvents from further damage. Subject yourself for a ultrasound
examination which will show the baby condition. Do breathing exercise
daily for 15 minutes atleast which will help you in this situation. All the best.
