is it just me ??? (rek'sai)

I find alot of trouble, clearing the first few camps with rek'sai. Even around lvls 5-6 and with upgraded jungle item, some camps give me alot of trouble to clear. I don't know if rek'sai takes too much dmg from jungle creeps or is her dmg is slow in killing them. The point is, unless i am lvl 7-8 with an item, jungle camps seem so hard to clear. If am jungling against a rek'sai all i have to do is follow her in the jungle and she is so low i can kill her with ease.

Why is this happening? Is it just me having trouble with her?
