Confused about this pill situation

Tia-louise

I’m on the mini pill and I’ve had a little thought that I might be pregnant and took at test last week it went to positive and then faded back to negative and I was speaking to my boyfriends mum about it and she said she got pregnant with one of her kids on the pill I’m going to take another test soon and then go doctors but I was wondering I took my pill yesterday morning and then as soon as I woke up I ended up having sex with my boyfriend and nothing ended up coming out of me and it normally does but I took my pill straight after and still nothing has come out need some advice 🤔
