Hi @sallyann1234 @eachtotheirown 👋 I'm in a similar situation but a bit further along.
(Just) 34 and TTC for about 18 months now. Went to gp in March for initial tests, fine for both me and DH. I had various bloods (thyroid, LSH/FH etc as well as progesterone) as well as a transvaginal ultrasound to check for fibroids, cysts etc. Back to gp in May and was referred, initial appt was end of July.
At this first appt I had an in depth discussion with the specialist about both our medical histories, lifecycle and what we've been doing to ttc (although only I went). Next steps are more tests for me - one to check for blocked tubes and one to check for adhesions in the lining of my womb. I have the second test in Sept and the other one I have to phone at the start of my cycle as it has to be done in first 10 days. Can take up to three months for an appt to be free so just have to keep trying! The specialist said my go had done a good job in getting all the tests done before my referral which was unusual, as they often have to do some of the basic stuff after the first appt which obviously slows things down.
Back to specialist in December and he said if we weren't pregnant by then it would be a referral for ivf, and with waiting times we would have passed the 2yr mark to qualify for unexplained infertility. Would be either one or two cycles depending on which ccg I'm under.
Not had the tube test but have two friends who have recently - one said it was fine and the other had a more painful experience. Of the tests I have had so far (and some precious unrleated gynae investigations) I've not found anything painful. My doc recommended taking painkillers before and after. One of my friends has PCOS and has been given Clomid (has to have some scans when starting to take) so hopefully that will be the same for you and will get you ovulating 
General advice was to make any lifestyle changes to be as healthy as possible (I need to lose a few lb from all the comfort eating), for DH to take some supplements and both go completely alcohol free. No need to worry too much about timing for ovulation as long as having regular sex 2 - 3 times a week.
Sorry this was so long but hopefully gives you a bit more of an idea of what's next - appreciate timings will depend on where you are in the country.
So good to speak to some people at a similar stage xxx
