You were on anti biotics about 2 weeks ago and had uprotective sex you are feeling sick your breasts very sore cramping really tired could be pregnant would have sympto?

Yes, it is possible that you could be pregnant. Antibiotics do not interfere with the effectiveness of birth control, so the unprotected sex you had while on antibiotics could have resulted in pregnancy. The symptoms you are experiencing, including sore breasts, cramping, and fatigue, could be early pregnancy symptoms. However, it is also important to note that these symptoms can be caused by other factors, such as your menstrual cycle or an illness.

The only way to know for sure if you are pregnant is to take a pregnancy test. If you are pregnant, it is important to see a doctor as soon as possible to begin prenatal care.
