Are injections every 10 days feasible or is it better to do them weekly?

I recently started with a dose of 7 mg which is equivalent to 0.18 ml of Estradiol Enanthate of astrovials, but I feel a little strange by day 8 or 9. I was previously on 4 mg of oral E and spironolactone. I'm not sure whether to stop taking spironolactone or change it to fina or bica?.
