User Profile
Hi, it is over 7 weeks since i had unprotected sex, i have taken the morning after pill but I'm still paranoid I'm pregnant! So far i have done 9 pregnancy tests (NOT using first urine in the morning) but surly they would be accurate at 7 weeks after sex? they detect 25mL of hpt, so are sensitive. THEY ARE ACCURATE AT 7 WEEKS AFTER SEX RIGHT?
thanks so much!

Hi,
Welcome to ehealthforum,
The urine pregnancy tests when done very early in pregnancy can show you false negative results as the kits are calibrated ones, so unless the hormone levels in urine reach a certain level, they do not show positive results. Urine pregnancy test kits usually start showing positive results after about 20 days post-conception (roughly corresponding to about 1 week after your missed/altered periods), so the tests done should give you accurate results (but there can be exceptions, as few women do not positive results during first trimester). The test should always be done on early morning first urine sample to get accurate results (pregnancy hormone HCG is believed to be in highest concentration in this sample, and you should avoid lot of fluid intake and caffeinated beverages in the night before taking the test). You may also consider taking repeat urine pregnancy test (on an early morning first urine sample) to see if you get positive results, or get it confirmed by a blood HCG test. Look out for development of any other new symptoms if pregnancy is suspected. Wait and watch for your next periods. If periods do not start within 10 days of expected period dates, or if you get abnormal periods, or if you suspect chances of pregnancy, consider visiting your doctor/gynecologist at the earliest for thorough examination (to confirm pregnancy related changes/signs in body) and blood/serum HCG level test (to confirm/rule out pregnancy accurately). Be in regular monitoring and follow-up with your treating doctor/gynecologist and report any new/abnormal symptoms immediately. Drink plenty of water. Take adequate rest. Maintain healthy diet. If pregnancy gets ruled out, and if you are not ready for pregnancy, but intend to remain sexually active, you should consider visiting your gynecologist to get started on suitable regular birth control measures to be protected (after your periods). Be regular with birth control use as instructed. Avoid having unprotected sexual contact if you are not ready for pregnancy.
Take care.
