Hi Zaza,
For acronyms "ER-AF-HSG-ET", you can see this link:
http://www.fertilityplus.org/faq/acronyms.html
I only know procedure at KK IVF:
Stage1:
1. Oral tablet (21 days)
2. Lucrin injection (start after D14 after the oral tablet)
3. U/S Scan after D14 of lucrin whether your hormone suppressing or not. If not then continue the lucrin. (your AF should be come on D10/D14 after Lucrin).
Stage 2:
4. If hormone suppressing, then buy puregon. Jab in the next day (for 8 or >= 10days) + lucrin
5. U/S scan on day 8 after puregon see the follicles enough size or not. If not enough continue puregon + lucrin for few days till follicles size enough.
6. Pregnyl jab in the next day at night.
7. After 2 days, ER (Egg Retrieval)
Stage 3:
8. After 2 days ER, then ET (Egg transfer)
9. Welcome to 2WW (2 week waiting). After ET, you can choose whether you want to get hormone progestrone jab or urgostane tablet (put inside your vagina). If you choose jab, then you must prepare yourself to come to KK to get jab for 14 days + you need to pay the medicine. For tablet, you do not need to come to KK + medicine is free.
10.D5 after ET, blood test to check your progesterone hormone.
11.D17 after ET, blood test to check your HCG level whether you pregnant or not.
Please correct me if I am wrong.
Which hospital you go? and under which doctor?
