You're still early in your cycle so I'd stick to one for now. What cd do you usually ovulate on average do you think?
I would do 2 a day from cd10. But if you got enough then no harm doing it now. Deffo from cd10 espically if you like you ovulate early xx
Was the frer from your fmu? Cos the fmu ic is fainter. Perhaps it was somehow not as strong, which seems odd if you've been holding it all night.
