TTC since 8 months. I have one tube block. From last 3 months I was on clomifene citrate. This month I had hcg 5000 injection on 14 day, said to have intercourse for 3 days and gave duphaston from 17th day. On 23rd, 24th day I found a brown discharge in vagina but not in panty. Again on 27th day n 28th same thing. Is this spotting is side effects of above inj. And tablets or anything else. Even though egg gets ruptured from 3 months why pregnancy is not happening in my case.
