It is a hard to tell because there are so many variables (anatomy, cervical mucus, follicle size, hormones, sperm, possible immune issues).
I imagine your timing was fine in my mind. The fasted swimmers they say can get there in 45 minutes the slower ones take hours at 12 hours supposedly ICI lose potency.
I did acupuncture before my inseminations, juicing fresh vegetables for extra nutrients, and yoga.
Garlic( I would eat a clove a day in the week of ovulation makes for copious mucus) , grapefruit, pomegranate and lots of hydration and alkaline vegetables for cervical mucus. Extra progesterone after 2dpo for a boost.
As for advice I imagine you have to look at your financial picture. Would you prefer to spend on more vials for at home inseminations?
Or look into assistance with a doctor or RE to check and make sure all is happening as it should in your body also an investment.( I spent over $1500 on testing)
Even with normal ovulating cycles with proper timing where sperm meets egg there is only a 20 percent chance that will result in pregnancy.
My last cycle that resulted in a bfp (fingers crossed it continues to go well) my doctor told me it wasn't common for it to take on the first medicated cycle ( clomid + trigger). I performed the inseminations ( I did ICI and IUI) he provided the clomid and ultrasound monitoring for the trigger shot.
My follicle wouldn't have released a properly mature egg without clomid assistance. In previous cycles I always ovulated on my own but without viable pregnancies due to an immature egg being released (we think). If it hadn't worked I think I was going to wait a few more months to save money again and try one more time at home but with just two vials but medication and ultrasound monitoring with my doctor again.
I hope it just works for you the next cycle and you get a bfp with a healthy full term pregnancy.
