Thanks for your query.
I have read your query & I understand your concerns.
From what you describe it appears to be implantation
bleeding most likely. Hence I advice you to stay relaxed and continue the medication till your beta hCG blood test
It appears you have implantation bleeding after embryo transfer
and soon you will get good news of pregnancy on your blood test day.
All the best.
I hope I answered your query. I will be available for any followup queries you have.
