No period negative test!

Hi I’m looking for advice, so I stopped taking my pill to try for a baby at the start of October and had the withdrawal bleed and so I was expecting a period start of November, it still hasn’t come and is showing no signs of coming! all the tests I’ve taken are negative and I am struggling to track when I’m ovulating or anything and I’m desperate to get pregnant :( I’m aware my body may still be adjusting to normal after coming off the pill but last time I tried I fell straight away, any advice? Please no negative or nasty comments I’m really upset and stressed about it all which most likely isn’t helping!
