Hi there, I have understood your concern and I will suggest you the best possible treatment options.
I will suggest you to get morning's first sample of urine tested for
pregnancy,in case of any doubt blood
beta HCG test and USG will be of help.
If you are pregnant then injection of
progesterone will not help to get periods or to terminate the pregnancy.
If youdo not want to continue with the pregnancy then you can opt for termination of pregnancy with
abortion pills under medical supervision safely till 9 weeks of pregnancy.
Please seek sex counseling about safe and protected sex activity,this will help to prevent unwanted pregnancy and STDs.
I hope this answer helps you.
Thanks.
