Thanks for your query,
There are high chances of yours to be pregnant because pregnancy
test checks hcg
. Further confirmation may be done by a scan. Regestrone
dont causes false positive.
Regestrone is a category X drug . Studies in animals or human beings have demonstrated foetal abnormalities. The drug is contraindicated in women who are or may become pregnant.
I suggest you to meet a OBG doctor soon for further management.
Take care and best of luck..
