Ok, so I'm new here and need some advice/some one just to listen

I'm 27, married, and trying to conceive. In the beginning of April I had a miscarriage, I was 4-6 weeks along. I've had irregular periods ever since, until this past month (july). After my period in July I used an ovulation kit, I got a positive LH surge on wednesday august the 1st. We also use "PreSeed", which was recommended by our doctor. We did the "baby dance", on tuesday the 31st, wednesday the 1st, thursday the 2nd, and friday the 3rd. Starting on monday the 6th, I had some slight white discharge (egg white consistency), and a little on tuesday. No itching, smell, etc. Tuesday the 7th I had a very faint pink (had to look hard to see it), only when I wiped. This morning (the 8th) Ive had very light brown, also only when I wiped. But nothing since around lunch time. My first pregnancy I didnt even know I was pregnant until I already was miscarrying, had bleeding and spotting throughout the month before, and what my doctor had told me mustve been implantation bleeding was an actual flow. I've been documenting everything since we've been trying (October 2011), so not sure what to expect anymore. I know if this was implantation spotting I'll have to wait a couple weeks to know for sure, but just needed some responses from people who've experienced the same things and can be supportive. Thanks so much!
