I did my IUI on 20 and 21st August 2018. Prior to that the stimulation given to me was follisurge injection for 5 days from day 2. This is my 2 nd IUI and prior to that have been in siphene and tried naturally for 3 months. My AMH- 0.4 No thyroid. Dr. had advised me to do beta HCG after 2 weeks. I did it today and result was 1.66. After sometime started having brownish like spots and discharge which stopped and started again. My periods date was also 3 rd September. What could this be? Can my beta HCG increase or is this my periods? I wanted to know as I am planning to go for IVF as two cycles of IUI are not success. Would like to know about this confusion and also with regards to IVF. Thank you.
