Thanks for your query,
This injection pubergen is a HCG injection
. It is given for ovulation and also for maintenance of pregnancy
especially in patients with history of abortion
. Xfer-f tab is given for healthy pregnancy.
It may work immediately also and may take some time also because pregnancy depends on so many factors. But in your case ,as you said every thing is normal ,i think you may get the results soon.
Best of luck and take care..
Hope it helps you..
