<s>[INST] Hi doctor!I have being using famymor birth control pill for three month now. Im worried my periods has changed. Im bleeding very light and I go on my periods for three days now, before using famymor I used to be a heaving flow and go on my periods for five days. Im worried. What comes to my mind is what if Im pregnant? Im pregnant? [/INST] HIT hank for asking to ChatDoctorI really appreciate your concern for the pregnancy as I'm always saying that nothing is 100% safe as long as the contraception is concern if you have such a history and clinical sign and symptoms that could prove the pregnancy then in my opinion it is better to get done the test and the best test is ultrasonography test, hope this information helps you take care and have nice day. </s>
