[/INST] Hi, it is okay. Just track your follicles' growth by repeated ultrasound and when your follicles is more than 17 to 18 mm, take injection for rupturing the follicles.  Be in contact with your husband for next 2 to 3 days after injection.  Take progesterone for next 2 weeks.  Do a urine pregnancy test at home after that.  You can try like that for 3 to 6 months.  Hope I have answered your question. Regards Chat Doctor.  </s>
