Problem in conceive. Am not conceiving?

I'm 29 yrs, married for 3 yrs, since last 3 months we are planning baby. I had vaginismus, was cured just 3 months back from the mental shakiness, and having successful intercourse without protection. In February,my period got delayed by 8 days and in between second line came in pregnancy kit with all the symptoms. When period started with heavy clots and pain, Doctor said it was spontaneous miscarriage. I did all the tests like USG,pus, blood, and all are normal except my uterus is retroverted. I have thyroid since last 3 years and consume thyronorm 50 mg daily, this test shows normal TSH 2.46. This month also we planned andy period got delays another seven days though there was no second line or pregnancy symptoms. I had never faced irregular period before this, why this is happening and I am not conceiving? I have upoloaded the semen analysis of my husband. Pls help me
