Thanks for your query.
I read your query and understand your concerns.
Following is my reply:
1) Inj choriomon you received was because of unruptured follicle which was must.
2) It is very early to get urine pregnancy
3) Wait for another 4 days and perform pregnancy test.
4) If you are eager to know pregnancy test get a blood test
called serum beta hCG
which is more confirmatory.
I hope I answered your query.
I will be available for any followup queries you have.
