Bleeding in the early stages of pregnancy is okay?

Hello doctor! I have menstrual disorders, for 2 months now I still haven't seen it. After going to a private clinic, they gave me medicine to drink to induce menstruation including: 1 pack of round white pills, 1 pack of daily birth control pills. The doctor instructed me to take the round white pills for 10 days, then stop taking the medicine and my period will come for 2-7 days. When my period comes on the 2nd day, I will take the daily birth control pills. But when I took the round white pills, I felt dizzy even though I had eaten. I took the 2nd pill and my period came, so I stopped taking the medicine. I went to the clinic where I was prescribed the medicine and asked, the doctor said the medicine would cause dizziness after taking it and told me to take the daily birth control pills as prescribed, and when I finished the medicine, come back for a check-up and continue treatment. I am very worried, maybe it is because I am stressed or have changed my lifestyle causing menstrual disorders. Will the medicine the doctor gave me have any effect? And will taking birth control pills regularly like that cause infertility? I hope the doctor can advise me, thank you doctor.

Hello Doctor. Recently, I have noticed that my belly is getting bigger, my chest also seems to be getting bigger, sometimes I feel chest pain and back pain near the pelvis. I haven't had my period yet and I only got 1 line on a pregnancy test. Did the doctor tell you that you are pregnant? Thank you doctor.

I am 21 years old and 23 weeks pregnant and have a swollen lymph node in my armpit. Upon observation, the lymph node is painless, soft and about 10cm in size. So I would like to ask if it is dangerous for a 23-week pregnant woman to have a soft lymph node in her armpit measuring 10cm?

had the contraceptive implant for 3 months. The first 2 months I had bleeding like menstrual bleeding. On the 3rd month, on October 27th, I had my period. Today, November 15th, my period has not come yet. I saw a little bleeding. I am so worried!

Hello doctor, I have a question for you. I started having my period on February 4 and 5, but it didn't come back until February 6. On February 10, my period ended and I started monitoring ovulation until February 23. The egg size was 21mm. So, can you tell me how long it will take for ovulation to occur? Is it possible for ovulation to occur at the end of the menstrual cycle? I've been monitoring to have a baby boy but it's too difficult. Please advise. Thank you, doctor.

Hello doctor, it's been 2 years since I had a cesarean section. I'm pregnant now but I didn't know so I took antibiotics because I had a cold. I'm afraid it will affect the fetus so I want to have an air-conditioned suction. Is that okay?
