Opinions please help 😩😩

Jen • CP 02/18 Praying this is my rainbow BFP 01/08/19

I’m now 4-5 days late on my period and my HCG doubled in 48 hours but it’s only at 38. Top test was yesterday morning and bottom is from this morning. I want to take things as they are, can you ladies be honest with me and let me know if I should proceed with caution? I feel like I see blazing positive at 11DPO and I’m like 16-17 DPO and still not getting blazing tests or HCG.
