hi, got 2 postive results with home testing and a negative at doctors. ive had slight spotting over past couple of days which could have been implantation bleeding. anyway as ive not has my proper period yet i want to keep testing just incase theres not enough hormones there yet and thats why the doctors test was negative but i dont want to keep paying £10 for the tests they sell at the chemists. in town ive seen some tests in home and bargain for around £1.50 i think they was called reveal but im not 100% sure. As anyone used these tests and are they as realiable as the more expensive one?
