Hi Jessabean, welcome to our little group, but sorry it's in such sad circumstances.
If I understood correctly, this is your second miscarriage? I'm so sorry.
If you got pregnant straight away after the first one I can imagine you might want a little break from TTC for a month or two at least? You must be exhausted and emotionally drained. I read somewhere that you're more fertile in the 6 months after a miscarriage, so I'm sure it won't matter if you give yourself a little break for a while. The right bean will stick when it's ready.
A faint positive is probably a good sign in a way - I imagine if you had higher levels of HCG the line would be stronger? It's probably just still leaving your system. My EPU told me to test in 2 or 3 weeks. I'm going to test on Tuesday - 2 weeks after my surgery and if there's still a line I'll test again a week later. I think it can take a few weeks for it to continue going down, depending how far along you were or how high the HCG levels had got.
My surgery was on the 27th, a day after both of yours, but then I am a year older than both of you, so that's fitting. 
I think I'm going to try to wait until after I've had a proper visit from AF before trying again, however once I've stopped bleeding my partner and I will definitely want to have sex again and we won't be using protection, so whatever happens, happens. I have already told myself that I won't be symptom spotting or testing until I'm definitely more than late, because I know AF can take a few weeks to get back to normal and there's no point getting my hopes up unnecessarily. Part of me is pretty terrified about getting pregnant again though. It's just been one long journey of anxiety and worry since I got my positive on the 18th Feb for me.
I'll be trying to eat well and exercise a bit more too... I lost my mojo a bit when I was pregnant, I was just too tired and hungry all the time so I ended up asleep during my spare time and eating anything under my nose.
RedRobin7, I had a similar comment from a gynae consultant years ago. I have endometriosis, one ovary (because I had one removed with a cyst) and a didelphic uterus (I had two wombs stuck together and had to have one removed as it was causing me major issues). My consultant told me not to wait too long to have babies (I was 21 at the time). That has been playing on my mind every so often, but hey - look at us, we both got pregnant! That's amazing, isn't it? And if we can do it once, we can do it again with sticky beans. :) I don't think we're past it. And yes, it might be harder for us both to conceive, but like I said, we've already done it once!
That's great about the counselling service, I'm so glad you're getting help. It might be useful to just make a list of things you want to discuss and then decide which one to start with. You'll probably find conversation leads on to the other issues from there.
I'm not nearby I'm afraid. I live in Derbyshire.
