Most of the ultrasound
scans start picking up fetal heart beat after 6-8 weeks of gestation. Go ahead with repeat ultrasound scan after one week (preferably transvaginal scan) to look for fetal heart beat and viability. You can also consider requesting your doctor/obstetrician for getting serial HCG levels tested. Doubling up of the hormone levels in 48-72 hours will show that pregnancy
is going on smoothly. If levels are not adequate, then external hormonal
supplements should be considered to be started to help you in preventing miscarriage/threatened abortion
Take adequate rest.
Drink plenty of water.
Maintain healthy diet.
Avoid any heavy work.
Avoid lifting heavy objects or climbing stairs or standing for long periods of time.
Look out for early danger signs like bleeding/spotting, increasing intensity of abdominal cramps and back pain
Be in regular monitoring and follow-up with your treating doctor and report any abnormal symptoms immediately.
