[/INST] Hi Welcome to Chat Doctor PCs is multifactorial disorder which leads to an ovulation and infertility. Try to lose weight by diet control and exercise. Get your blood sugar levels done apart from other hormonal investigations. Symptoms (Pain) you are experiencing after taking Chat Doctor injection (for egg rupture) is suggestive of ovulation (egg rupture). It's a good sign and you should utilize this opportunity and have sexual intercourse to increase your chances of getting pregnant.
