Any insight would be appreciated!

I have had increasingly darker FRER tests since 9dpo. I am currently 14 dpo and one day before missed period and I had some veryyyy light brown spotting last night and even less this morning. It has stopped and it was very minimal.

I had my beta hcg checked yesterday at 4 weeks and it was 62.

I will repeat blood work tomorrow and praying that it doubles.

As I had a missed miscarriage in March and a chemical last month, I am so fearful of losing another baby.

Could this be implantation spotting this late? Should I be worried my hcg was only 62?

Thank you in advance <3
