Hi Legend
You sound v similar to me- so sorry to hear about the miscarriage, it's utterly shit isn't it?
I had a missed miscarriage in June last year- started bleeding the day of my dating scan, one day short of 13 weeks. Complete devastation.
Like you, I fell pregnant straight away with number 1, had stopped taking the pill after more than a decade.
Number 2 last year was the exact same- barely had a withdrawal bleed from the pill, then boom I was pregnant.
So have been TTC since July- I never knew what a journey it could be, working out dates, obsessive knicker checking, making sure we did it at the right times, being convinced this would be THE month only to be left utterly disappointed.
To get to the point, it's been over 6 months TTC now & absolutely bugger all. Thankfully my periods are regular and things seem to be ok.
At first I tried to reassure myself that I would be pregnant pretty quickly and definitely by the end of 2016- but no this was not to be the case.
Arriving at my due date in December was really tough, more than I thought it would be- a lot of people have commented that once you go past your due date you are "ready" to fall pregnant again- but that doesn't seem to be the case for me yet.
I've been ready to fall pregnancy since July!
Also to add, I've been using OPKs since last summer- bought them off Amazon the week after confirmed MMC as I thought we should use all the help we could get. Also did BBT for a couple of months but couldn't be arsed to carry on- from what I did, it appears I am ovulating.
The most exciting it's got over the last 6 months is having positive OPKs!
I know we have been having sex at the correct time (according to the OPKs) so it's so very frustrating.
To top off all my desperation and sheer frustration, I am going to turn 39 this summer so I really do not have time to lose in this game.
I look back wistfully at 10 months ago- sudden & unexpected BFP, and feeling relieved that we'd have baby number 2 by the end of 2016, at the grand old age of 38 and we wouldn't need to go through the stress of TTC.
If only that were true 
Sorry this has been such a ramble and I have no good story to share with you, but I wanted to say thank you for posting and I truly know where you are coming from.
Good luck to us both!
