need your opinions girls

ok I'm worrying myself stupid I had a mc late August found out I was slowly losing it as I was testing and the line got weaker and weaker over a few days then I started to bleed, i have found out last week in again pregnant been testing like crazy as its generally the only thing that makes me feel better about the situation I'm so worried it's going to happen again this time. I'm sure the last two test on the picture are lighter then the other couple previously from this morning, is it good progression, why would them last two be lighter then the darkest ones from this morning.im getting myself in a right mess hear.. x
