Hi,
Welcome to ehealthforum,
If pregnancy has been confirmed, and if serial HCG levels estimated have shown consistently rising levels, then chances are that pregnancy is going on smoothly (especially if you are not having any signs or symptoms indicating impending miscarriage or threatened abortion). Doubling up of the hormone levels in 48-72 hours generally shows 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. An early ultrasound scan done (preferably transvaginal) will help to know if pregnancy is intrauterine or ectopic along with confirmation of gestational age and viability (confirmation of fetal pole and heartbeat). Be in regular monitoring and follow-up with your treating doctor/gynecologist or consider taking a second opinion from another gynecologist and report any new/abnormal symptoms immediately. Look out for danger signs like increase in intensity of abdominal cramps, increasing back pain, fresh bleeding etc. Avoid lifting any heavy weights and avoid heavy work. Avoid standing for long durations and avoid climbing stairs. Take adequate rest. Drink plenty of water. Avoid use of caffeinated and carbonated beverages.
Take care.
