Recent bloodwork shows fsh at 2.0 & lh at 3.6 --- are these concerning? they are on the lower side of normal --- should i be at all concerned?

With both of these numbers being on the low side, that implies that you are just in a certain phase of your cycle where you are starting to ramp up for the next phase. We can consider you a regular woman of child-bearing age and capability.
