<s>[INST] Hi..Iam diagonised with foliculer stuty,I had taken on fertyl 50mg from 2nd to 6th day of periods at night after food.  On 14 day my egg is 22mm and doctor suggested to concieve. we concieved on 14 and 16 days.But now after 35 days the pregnancy test shows negative results. what could be the reason of negative test and even  I didnt got period yet .Please suggest me what to do to get pregnant, doctor we are looking for pregnancy desperately. [/INST] Hi, Thanks for writing to Chat Doctor. Though your pregnancy test came negative you may be pregnant. This can be confirmed by serum b-ChatDoctor level. Sometimes after fertilization it takes time for impaction of embryo. Other possibility is after egg became 22 mm it could have become a cyst instead of rupturing.  After one week I suggest you to get one more ultrasound scan done. For increasing chances of pregnancy you can 1)after taking ferry tablet when your egg is of size more than 19 mm you take Chat Doctor injection under your doctor guidance. 2)after confirming your egg is ruptured you get intrauterine ingestion(GUI) of semen by your doctor. But before getting GUI you should get tubal patency done. Hope I have been helpful. Regards Chat Doctor.  </s>
