I am 43 and currently using estrogel only but i seem to need a high dose, 6 pumps a day, and still having symptoms of low estrogen. should i increase?

Talk to your doc!: You didn't mention your specific symptoms of low estrogen so perhaps they're not related to low estrogen after all. Whether to increase your dose is best addressed by your prescribing physician. Another option is to consider another form of estrogen replacement, preferably something transdermal, say patch or spray. Or just try another gel/lotion/cream product. Some products absorb better than othe.
