Hi there, I have understood your concern. I will suggest you the best possible treatment options.
1. First of all do not panic.
2. All your symptoms can be related to
pregnancy. But the most important sign of pregnancy is a missing period.
If you have history of unprotected sex act in the fertile period of cycle, means between day 10 to 20 of the cycle, then you stand chance to get pregnant.
3.If you have crossed your expected date of the cycle, you need to confirm the diagnosis of pregnancy. In such case, 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. If you happen to start your periods, then you need not worry about the pregnancy.
If your pregnancy test is negative, then you can induce the periods with
progesterone tablets. Your treating doctor can guide you further about the doses and withdrawal bleeding of the same.
5. Even if you are pregnant, you can opt for termination of the pregnancy with medicines safely till 9 weeks of pregnancy under medical supervision.
I hope this answer helps you. Thanks.
Dr. Purushottam Neurgaonkar.
