Pre-seed

Been trying to get pregnant for about a year now, I have a 5 year old and now I think it’s a good time to grow our family of 3. I have been extremely irregular for 2 years. Started seeing the DOC about my irregularly back in March and started provera it’s helped a bit but my doc finally gave me comiphene and on the day of ovulation I used the pre-seed I heard and read about. I feel like it’s my fault, mainly because I don’t get my period regularly. If this doesn’t work idk what will and probably feel extremely incompetent.
