7dpo first month using fertility gel

i am 7dpo and absolutley dying to pee on a stick.... it was our first month using fertility lube so i am hoping that it has done the trick and helped the little swimmers along their way.
i have no symptoms atall apart from a strange rise in bbt...99.76?
we already have 2 children, our son is 8 and our daughter 9.... i had absolutley no symptoms with them this early either.... not untill i was about 6 weeks and then the sickness kicked in good and proper!!! :-/
anyway... has anyone tried any different brands of fertility lube and rate it? i have read some really good reviews in people getting bfps straight away after previously trying for months xx
