I recently gave birth to my second child via C-section on July 13, 2020. My baby boy weighed 3.7 kg, and my health has been normal. However, today I noticed two lumps in my armpit, which are painful when touched. Could you please advise me on how and where I should get examined?

Dear Doctor, I would like to ask for your advice. I had intercourse one day before my period and took emergency contraception the next day. Is there a chance that I could be pregnant? I would greatly appreciate your consultation. Thank you, doctor!

Hello, Doctor. I would like to ask a few questions and hope you can help me with the answers. My menstrual period started on January 5 and ended on January 9. On the 14th, I had intercourse with my husband, and after two weeks, I went for a check-up and was informed that I was pregnant. On February 6, I went for another check-up, and the doctor said I was 4 weeks pregnant.

I am 25 weeks pregnant, and my baby moves a lot in the uterus and lower abdomen. Is it dangerous for the fetus to move frequently at 25 weeks? Will frequent fetal movements affect the cervix in any way? I look forward to your advice. Thank you, doctor.

I have polycystic ovary syndrome (PCOS) and have been receiving treatment from a local doctor for the past month. I recently took a pregnancy test, which showed one dark line and one faint line. However, when I tested again the following day, only one line appeared. I then underwent an ultrasound, which did not detect a pregnancy, but my endometrial thickness was measured at 14mm. Does this mean I could be pregnant despite the ultrasound results?

My boyfriend and I engaged in external genital rubbing with only a thin layer of clothing in between. I want to ask whether external genital rubbing can lead to pregnancy. Thank you.

I underwent a gynecological examination a week ago and was diagnosed with cervicitis. The physician prescribed vaginal medication for a duration of 10 days. I only administered the medication once in the evening, and the following morning I noticed spotting. I am uncertain if this is due to my menstrual cycle or a result of the inflammation. The bleeding persisted for two days, although the volume was minimal, and then ceased. The day after that, I resumed the vaginal medication for one day, but experienced bleeding again. Therefore, I would like to ask, after observing bleeding following the use of vaginal medication, should I continue with the treatment? Thank you, Doctor!

Dear Doctor, Could you please tell me if the absence of the embryo and yolk sac at 5 weeks means anything?
