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 might be aware that in a woman with regular cycles day 10 to 20 of the cycle is the most fertile period of cycle . If you have unprotected sex act in the fertile period,then You have chance to get pregnant.
3 ) In your case, I will suggest you wait till the expected date of the cycle. If you happen to cross your expected date of the cycle, then I will suggest you to get morning's first sample of urine tested for
pregnancy. In case of doubt blood
beta HCG test and USG will be of help.
4 ) Even If you are pregnant, you can opt for termination of the pregnancy with medicines safely till 9 weeks of pregnancy under medical supervision.
If you are not pregnant then you can seek help of Your treating doctor for getting the prescription for your symptoms.
I hope this answer helps you.
Thanks.
Dr. Purushottam Neurgaonkar.
