Help!! Feeling so insecure ๐Ÿ˜Ÿ

In January I had a light positive test that never got any darker over time. I had an ultrasound at 5 weeks which showed nothing, and ended up miscarrying over the next 3 days ๐Ÿ˜ž

On the 4th of July I had a really strong BFP at 10dpo (like, BRIGHT pink line), and it has gotten darker over the last week (see pics). I also have extremely sore boobs, and am completely exhausted. My symptoms are good, but I had those last time too and it did t work out. Anyways, because of what happened in January, Iโ€™m feeling really insecure and so worried that itโ€™s not real, like what if this pregnancy is empty too.

I know I need to give this to God, because either way thereโ€™s really nothing I can do about it, but does anyone have any advice on staying positive? My drs office wonโ€™t even see me until Iโ€™m 8 weeks. They donโ€™t want to bother if youโ€™re going to have an early miscarriage.
