Help!

Mercedes

I’m a week late! I’ve been off the pill microgyn since November 27th and had my naturals period the first week of January and nothing since! I’ve taken a cheap £1 pregnancy test from our pound shop and it’s negative! I’m booked to see my doctor but my appointment isn’t till March 5th! Both me and my fiancé are ttc and it’s scary that I could be but I’m not? I don’t know what to do any advice would help massively ❤️
