Positive line

Depends on your cycle, how long is your cycle? If it’s 28days it should be darker. Monitor it for a few more days if it’s still not getting darker you may need to contact your doctor as it could be a sign of ectopic or early loss.

My cycles vary typically 32-36 sometimes?

Definitely wait a few more days and monitor the progression

This is a good sign. Keep testing until you get a dye stealer. Congrats x
