Only Fertile in October

Alright y'all, I'm currently 16 weeks and 4 days! I was just sitting here at 3 am thinking about how blessed I am for this little belly and such because this is my 3rd pregnancy and it finally stuck! 💜🌈 But, it also made me realize...I've literally gotten pregnant 3 years in a row in the same month around the same time! I've only ever been pregnant in the month of October, in 2017, 2018 and then this one in 2019. Does anyone else have their "lucky month" or am I just a weirdo? Just a crazy thing. Even with this pregnancy I told my partner in September, " Get ready baby, October is my fertile month, this will be our lucky time." And at the time I was joking, when I took the pregnancy test 3 days early before my period I was joking too! But boom, a very faint line! I pee on a stick every month in Hope's of the lines, but am always disappointed, but this time I was so right and I think it's because my body and mind just know that October is my month! Anyone else have this?!
