<s>[INST] Hello doctor, I usually get regular periods. This month my period got delayed by 11 days as of now and i took two pregnancy tests (one today) and both show negative. is there a chance where i could still be pregnant and why does the home pregnancy test show negative. I dont have any pregnancy symptoms [/INST] Hi As two pregnancy tests are negative and you also do not have any clinical symptoms , most likely you are not pregnant.  If you still have any doubts , blood beta HCG test will be of help to rule out pregnancy. Negative pregnancy test with delayed periods can be just due to hormonal changes. You can opt for onset of the periods,  or if you want you can induce the periods  with Tab Regestrone Twice a day for 5 days. I hope this answer helps you. Thanks Dr Purushottam Neurgaonkar. </s>
