Thank you for your query.
diet, you would not be given very strong doses, specially to have a very strongly positive pregnancy
However, there is now only one way to confirm
You cannot go for a blood HCG test also, as your HCG diet shots might interfere with that too.
You can visit a gynecologist and go for a transvaginal ultrasound
scan, as that would show evidence of pregnancy if you are indeed pregnant.
