Update- Chemical: Only faint lines on FRER??

Question

It appears I am having another chemical pregnancy. Two in three months. My FRER peaked at 4w1d and then began to fade. It is now nearly negative today at 4w4d; however, Wondfo is still SIGNIFICANTLY darker.

Original Post:
I got my first very very faint line on wondfo three days ago. I’ve been tracking the progression daily and I think it is getting darker? However, my FRER tests are barely visible. Has anyone experienced this? Period is due tomorrow and I’m hesitant to get excited. I had a chemical in May and previously had two losses before my two healthy children so I’m a habitual tester. I’ve always tracked progression with FRER but this really has me concerned. Top pic is progression from Sunday to Tuesday. Bottom pics are this morning.

Answer

Are you using the same sample for the frer and the wondfo?

Answer

Positive, i see faint line on frer

Answer

I honestly find Frer to be really light and hard to read always. The lines look great on the waldorf

Answer

I’ve noticed frer has not been super sensitive

Answer

FRER taken two days apart. I would expect it to be darker especially given the most recent wondfo and how close I am to my period.

Answer

You won’t see a progression every day it be every 2 days as it takes 48 hrs for hcg to double. They are getting darker however this isn’t a way of seeing if the pregnancy is sustainable only way is via bloods. Congratulations 🙌
