Hello, Welcome to HCM, I am Dr. Das
Look, your symptoms are really indicative of early signs of impending miscarriage. But, the ultrasound scan indicates presence of live fetus till now.
SO, you have to be treated meticulously.
You have to do -
1. take complete bed rest.
2. You have to take progesterone
supplement to prevent miscarriage.
3. You have to be given HCG injection
4. Folic acid supplement
should also be considered.
5. Ultrasound scan should be done every 7 days.
6. Broad spectrum antibiotics like amoxycillin
group of drugs to control the urinary tract infection
So, consult with your treating doctor about these.
