Hello, If you are not facing any pregnancy symptoms and periods do not occur, then repeat a pregnancy test after 1 week. If you experience symptoms like lower abdomen pain then visit a gynecologist and get beta hCG test done to confirm pregnancy.

Do Beta Hcg. Intrauterine pregnancy can be  seen in scan after 5 weeks or more than 1500 beta Hcg titre. Don't ignore symptoms like pain in lower abdomen, giddiness, scanty bleeding etc. Monitor beta Hcg levels after  48 hrs. Repeat scan after a week or earlier if needed.

Some are late responders and sac appears later...so don't panic. Do your HCG levels as suggested! Repeat scan after one week. Mean while keep a check on your symptoms and give a feed back to your gynaecologist if there is any pain in the lower abdomen or any dizzibess or a slight trickle of bleed ....please report or go to the hospital.

Do your hcg levels How many weeks amenorrhoea

Can be a normal/ tubal pregnancy. Do blood Beta HCG 48 hrs apart which should double. I personally feel to to wait till ur symptoms. Doubling will rule out a deadly condition of tubal pregnancy and u can relax and enjoy ur pregnancy as well.

It may be a very early pregnancy. Do not panic. Do serum ßhCG. Do it twice, 48 hours apart. It should double in a normal pregnancy. If you experience giddiness, pain or spotting, report to emergency immediately. Also, repeat your ultrasound in a week, preferably with same sonologist

There are various possibilities of this. If there are no untoward symptom and periods don't start. wait for a week and repeat pregnancy test. If there are pregnancy like symptoms, giddiness or pain in lower abdomen, get Serum Beta HCG done and show the report to Gynaecologist.
