Trying to conceive, no signs of period. HELP!!!

I’ve not have a period for about 2 years maybe more, I have been with my partner for a year now and we have been trying to conceive, I’ve been to the doctors and had been asked to come off my birth pill for 6months and see if there is any sign of a period, still no sign, I’ve been getting pregnancy symptoms but still no sign of pregnancy when taking a test????

Can you ladies give me anymore help than I’ve already received!
