faint positives up until after your missed period ?

Question

I haven’t missed my period yet. It’s supposed to show tomorrow . All week I’ve been getting faint positives. They haven’t gotten darker or lighter just stayed the same . Should my line be darker after my missed period ? 
-btw no spotting or bad cramps .

Answer

Some get darker, some don’t. See a doc to confirm, maybe wait til you’re a few days past your missed period. Ask for a blood test rather than just a urine :)

Answer

Probably a chemical :/ I had a bfp that was really visible st 10 dpo and ended up started my period 2 days early :/
