@Suzie I don’t know what this is? Please explain
I wouldn't stress too much, after my missed miscarriage in late March I tested positive for 4 weeks after as a strong positive if your worries contact the epu/epac at your local hospital and they will scan you the darkness of the test goes by the time of day you take the test, I'm 9 weeks 3 days and took one for fun with friends and it was very light as was the evening and baby is fine x
Pregnancy tests get less reliable by 9 weeks. When hcg is too high, tests can actually get lighter so don't rely on them as an indicator for a healthy pregnancy. My symptoms also dipped at 6 weeks and that can be very normal (I'm pregnant with my 3rd). I'm now 7 weeks and have some mild symptoms, but nothing crazy and that happened to me last time, too.
If you are nervous, always talk to your ob but the tests getting lighter is not uncommon.
