Good sex

My husband and I always have good sex. We have been married for 7 years and have 3 sons together. I don't use any contraceptive because I tried before with different ones and they just don't work for my body, they make me bleed alot and for many days. We only rely on plan b or pull out method. We both want to try for a girl though, so lately every time we are doing it because it's so nice he would ask me if he can cum in me or pull out, and me feeling so nice also I always don't want to ruin the moment for both of us, so I tell him just to cum inside. Next morning when all is done I'm left confuse whether if I should buy the pill or just let things be. For him he is always fine with any, whether I buy the pill or not. Sometimes we'll buy the pill and I won't take it and luckily I didn't get pregnant, which makes me sad sometimes also. Sometimes I'll take the pill and regret taking it again. Like now ill be ovulating on Friday which will be our anniversary day, obviously we'll be having good sex but now I'm confuse if I should let him come inside or pull out and this time around I'm certain that if he does come in, I'll definitely fall pregnant. I'm just so confuse......
