Hi, My wife is 8 days late for her period. During ovulation she was under treatment for Acne and was prescribed Doxy 1, 2 tablets per day. After missing her period she has not been well, body temperature looks above normal. She sometimes feels nauseous specially after having food, lightheaded sometimes which have increased in frequency. What is worry is that she is sometimes having sharp pain in the right side of the abdomen. Which comes and goes and is more like throbbing pain. She had undergone USG on 11.11.17 and reports were normal. Blood test for T3, T4, FSH, LH, Prolactin, DHEAS was also normal. We have done 2 home pregnancy tests on 7/12/17 and 11.12.17 both came negative. All other symptoms indicate pregnancy but the tests are coming negative. Also if this is a case of pregnancy will it be safe to continue with it as she was conceived when she was having high does of Doxycycline? What is happening with her? Consulted a local Gynecologist who asked to wait for few days and again test for pregnancy. She has gained around 5-6 kgs in the last month. She is also having a white / colorless vaginal discharge for the past few days and this has increased from the last 12 hours. The color has changed from colorless to light yellowish. Can this be any kind of infection?
