Fustrated

So, my husband and I have been trying for about 6 months. I had a mc/chemical in July last year. We started trying again in December. I have two apps with 2 different period start days. My glow says Friday the 26th, but my other app, which has never been wrong says I should've started yesterday. I took a test and it's negative :(. I'm getting frustrated because we seemed to hit my ovulation days but haven't been able to get a positive test.
