Hi there, I have understood your concern . I will suggest you the best possible treatment options.
1 ) First of all do not panic.
2 ) As you have mentioned that you had sex activity in the month of June and you had your periods after that in the month Of July,this means that you were not pregnant.
3 ) You had some unusual bleeding pattern in the Month of August. I want to assure you that you need not worry about the
pregnancy.
4 ) For your other symptoms, I would like to suggest you to get a physician opinion , please check your blood pressure and
kidney function tests. USG will be of help to know the reason for your abdominal symptoms.
5 ) If you are having occasional sex activity, then please use barrier
contraceptive method like condom, this will help you to prevent the unwanted pregnancy and STDs.
I hope this answer helps you .
Thanks.
Dr. Purushottam Neurgaonkar.
