Thanks for your query.
I read your query and I understand your concerns.
Following is my reply:
1) If you think there is LUF, It is wrong. Because you had already conceived which means you are ovulating normally.
2) Keep getting follicular growth scans and have intercourse after taking Inj. hCG
for ovulation which will time ovulation.
3) You may not need IVF. You are likely to conceive naturally and might need cervical stitch in second trimester as per your history
I hope I answered your query. I will be available for any follow up query you have.
