Anyone here use DIGITAL CLEARBLUE ? If yes how many times u can use that ? Bcoz i want to buy Digital instead of Ordinary .

Im 3 days delay already , and i took 2 test , but result r negative . I want to try again but instead of buying ordinary i want to buy the digital . Its expensive yes , but buying ordinary for few times its almost same price as digital . But i want to know first if how many times u can use that . TIA for those who will give some attention on my post .
