Could I Be Pregnant?

[PETAL]

Hi, I am sitting here in tears at the minute. I am 12 dpo and have had alot of preg signs over the last week- creamy cm and lots of it, darker area around nipples, come out in spot (never do usually), headaches, tiredness, moody, metallic taste in mouth, waking up middle night, and I have had lots mucus at back throat/sore sinuses last week. I did a pre test 2 dys ago - clearblue 4 dy early and there was a pencil thin vertical line going through the horizontal control line (bfp?). So I did 2 digital tests but both said 'not pregnant'. I thought I would wait two days to test again. So today arrived and I did a 6 day early early response test. It came up BFN. I have been using cbfm and testing past ovulation (just by poas and looking at result) to see estrogen levels. They appeared high level yesterday-on one line and the other line which shows LH came up too so I thought it could be hcg (as they say o tests can detect that same as LH). But today the estrogen level appears down and no other line. My temp has also dropped from 36.7c (test 8am past week) to 36.2c today (6am) My af is due on Sat or Sun (2/3 dys time). I lost a baby two months ago and being pregnant again is the only thing that will help me move on with my life.. my husband and I so want a baby.. we stopped drinking, only eat organic food, take all vits, bd at right time (used cbfm). Do any of you think I could be pregnant or should I just accept that I am not?
