Tanz - biiiigggg hugs to you! It's only natural to still feel sad but I'm so glad your back on the forum xxx
Littlewing - smoking does interfere with your egg quality and with attaching the embryo. I managed to quit smoking for a while, then started up again, then quit again - and everytime I smoked was when I had BFN!! But end is, no smoking is the best policy.
I know it is extremely hard and difficult but you HAVE to be patient. Being impatient and thinking something is wrong after only 7 months will only put more stress on you and DH and it will take even longer to fall preggos!! Trust me, I've been doing this for 18 months and here's girls here that's been ttc even way longer than I have!
It's very very normal for a couple to take up to 12 months to conceive so you still have 5 months left. How old are you if I may ask? If your under 35 an FS won't see you unless you've TTC on your own for 12 months. If your over 35, it's 6 months.
Try and stay strong - it will happen
