Hi there, I have understood your concern.
If you have history of unprotected sex act, if you have history of regular cycles then your dates of sexual activity fall in the fertile period of cycle.
And there us possibility of getting pregnant.
Your symptoms can not be directly related to
pregnancy. The very first and important sign of pregnancy is a missing period. As you have rightly said that it will be too early to expect pregnancy symptoms and get urine test done.
I will suggest you to wait for your expected date of the cycle . If you happen to cross your dates, then please get morning's first sample of urine tested for pregnancy. In case of doubt blood
beta HCG test and USG will be of help.
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 you.
Thanks.
Dr. Purushottam Neurgaonkar .
