More sensitive pregnancy test darkening but other brand unchanged for days

[ShyLavender]

So I’ve been testing on two different brands one is 10mIU sensitivity and one is 25mIU. This morning there was a noticeable jump on more sensitive test but no change in nearly 4 days on other. Yesterday I had some nausea when opening fridge and nothing today. So confused. The tests are from 12dpo to 16dpo. Thanks so much I’m losing the plot

Step away from the tests. They are showing positive. It’s still early days.

Try and enjoy the moment.

I also understand the need to test and would love to listen to my own advice.

Updating as I know I was desperate to find outcomes. Diagnosed with pregnancy of unknown location this morning. Waiting to see if it’s ectopic or missed miscarriage. Hope anyone reading this has a better outcome x
