Hello mam, I'm doing infertility
practice for many years and my experience so far is that you probably are clomiphene
resistant to some extent at least. Injection you just got is FSH which will increase your follicle size and maturity so that when it ruptures there are better chances of pregnancy
. In case the conception doesn't take place this time then from next cycle your gynecologist might like to prescribe you higher doses or a different pure form of FSH (recombinant form) so as to achieve better quality of egg. Don't worry and relax for the time being. Wish you all the best.
