Line variation?

Paige

I had a miscarriage last cycle at just shy of 6 weeks. I just found out Sunday I am pregnant again. I think I’m 6 weeks 1 day today. I am VERY anxious about this pregnancy considering my last experience. My midwife put me on progesterone which I’ll take for the first time tonight. I am testing like crazyyyy. Very aware this is unhealthy but I can’t stop. I also understand line darkness doesn’t determine viability of pregnancy. But I feel like some tests are lighter/darker than others? I’m just worried. I haven’t had any major symptoms except last week I was incredibly tired. Yesterday I felt great, which honestly makes me worry even more.
