Provera users

After taking provera to jump start af, did any one have it still be very light?
​TMI, but I haven't had af since January, took provera for 5 days, 4 days later(today) af starts but it's sooo light. Not enough to fill a lite tampon. 
​Is this normal? Should I expect it to get heavier? Just confused. I thought after so long it would be much more
