Hello Ms Green
welcome to HealthcareMagic
If you are sexually active and had unprotected sex then there are always chances of getting pregnant.You are experiencing the signs of
pregnancy like :-
missed period;tender breast;
frequent urination .
The best thing is to get a urine pregnancy test done at home with a kit available at local chemist or get it done at a pathology laboratory.The test report will give confirmation of pregnancy then you can decide on the further course of treatment by consulting a doctor.
