Anyone else?? Gender intuition??

I'm 15 weeks along with my second baby (3rd pregnancy) ive had 2 boys previously (one m/c) at first i kept reffering to my bump as a girl/her and since about 13 weeks I've been calling my bump a boy/him...idk if its mothers intuition or if its just everyone else getting in my head about my having another boy.. what do you mummas think? I go for my early gender scan next saturday but the waiting game is killing me!! I just want to start buying gender related baby stuff. my mum had 4 girls and my MIL had 4 boys... (we want a little girly this time but we'll be happy either way as long as baby is healthy!) With my first i had no interest in picking a girls name only boys names now with this baby i have no interest in picking a boys name only a girls... i let my partner pick a boys name as i cant pick one i love like my firsts sons name and i am in love with the girls name we have picked but im still not sure on the boys name my partner picked. I'm going crazy thinking that if its a boy he wont have a name!
