You are certainly not rambling at all. With my current predicament I could ramble away a lot more than that so I know how nice it is to get it off your chest.
I am in Australia and I think we use different units of measurement to England. Do you know what days of your cycle the tests were performed on and what unit of measurement they are measured in, as this makes a difference.
I am no expert so I quote from a fertility book written by Dr Sandra CABOT:
Test FSH on day 2 or 3 of cycle. Normal range 2-20 U/L. The ratio of FSH to LH should be close to 1:1.
Test oestradiol (E2) on day 2 or 3 of cycle. Normal range 100-200 pmol/L.
Test LH on day 2 or 3 of cycle. Normal range: Less than 7 U/L.
When your nurse says your E2 was on the low side, I assume then this is not a day 2 / 3 test? Again, I am no expert, so here is a tidbit I found on the net about estrogen levels and egg quality:
Get estrogen blood test just before ovulation. Peak estradiol is between 500 and 1000 pmol/litre per healthy follicle. When cycle monitoring, ask your clinical team what your peak estrogen was: bigger numbers are better. If the level is towards 500 (or lower) per mature follicle, then egg quality may be a concern.

I suppose you could look all this info up for yourself if you want with good old Dr Google, so I am sorry to quote you a bunch of statistics if this is not what you are after, but rather just want to vent.
I too am no spring chicken and am about to embark on a 4th IVF cycle, so I know the frustration. Time gets away from us doesn't it. You don't expect it to take so long to conceive number one and then by the time you go through pregnany and breastfeeding, our time is just about up and number two doesn't happen as easily as we would like.
So you are starting with medical assistance. What is your next step from here?
