Hello, and I hope I can help you today. If you have been having unprotected sex, there is a possibility you could be pregnant. Pregnancy symptoms vary widely between women, and the symptoms that are commonly associated with pregnancy like nausea, bloating, breast tenderness and spotting can also indicate an irregular ovulatory cycle. But the most common sign of pregnancy is missing your period. So if your period is late or abnormal, I recommend purchasing and performing an over-the-counter pregnancy test and performing it according to the package directions using your first morning urine sample. Regarding ectopic pregnancy, a history of a pelvic infection is a risk factor for ectopic pregnancy, but it is not a guarantee. So if you confirm that you are pregnant, you should seek prenatal care early as your physician will need to order an ultrasound to confirm the pregnancy is in the right place. I hope I was able to adequately answer your question today and that my advice was helpful. Best wishes, Dr. Brown
