I am 6 weeks pregnant second time. 6 months ago i went through missed miscarriage. This time one week ago I went through ultrasound. The sac size was 6 weeks when i was only 5 weeks pregnant nearly 1.11 cm. Doctor put me on folic acid tablets along with dupbaston 2 times a day. Now after 8 days i feeling like my breast sweling and pain is reducing. I am so much worried. I donot want to go through miscarriage again. I want to ask what you I do to save my preganncy. Should I ask doctor to start hcg 5000 injections for safety on pregnnacy? Please advice me.
