losing my mind!!!!

Evamarie

So my last period was may 7 and I haven't had a period since then( almost five months) . I took a pregnancy test even went to the doctor about 2 months ago and nothing but negative. on Saturday I took this test and I feel there is 2 lines but then took the digital and it was negative. I've had a miscarriage in December of 2016 and I've been trying to conceive since April of 2017 any advice ?????
