63 DAYS SINCE LMP. NEGATIVE HPT? COULD I BE PREG? ?

Question:

HI,
MY HUSBAND AND JUST STARTED TTC. I STOPPED THE PILL IN NOVEMBER. AFTER STOPPING THE PILL I HAD A 26 DAY CYCLE, THEN A 28 DAY CYCLE, THEN A 46 DAY CYCLE AND MY LAST CYCLE WAS 47 DAYS. I AM NOW AT DAY 63 SINCE MY LMP. ABOUT 16&17 DAYS AGO I HAD A MJAOR (WORST EVER) AND CRAMPING ON MY LEFT SIDE. ABOUT 12&13 DAYS AGO I HAD SOME SPOTTING (VERY LITTLE AND BROWNISH THEN PINKISH)I NEVER HAD SPOTTING BEFORE. I CHECKED MY AND IT IS SORT OF LOW AND DEFINATELY SOFT AND CLOSED TODAY. I HAVE TAKEN SEVERAL PREGNANCY TESTS AND THEY ALL COME BACK NEGATIVE!! IS IT POSSIBLE TO BE PREGO AND STILL BE GETTING A BFN?? I HAVE READ A COUPLE OF POSTS WERE PEOPLE DIDNT GET BFP UNTIL 8-10 WEEKS. I HAVE NO IDEA WHEN I OVULATED SO THATS CONFUSING IN ITSELF. WE BBD'D JUST ABOUT EVERY SINGLE DAY OR ATLEAST EVERY 2 DAYS SO IM SURE WE DID WHEN I OVULATED.
ANYONE WITH ANY ADVICE OR SOMEONE WHO HAD A SIMILAR EXPERIENCE PLEASE GIVE ME SOME FEEDBACK!!! THANKS SO MUCH
(IM MAKING A GYNO APPT. TODAY FOR A BLOOD TEST)

Answer:
Hi, I had my LMP 5/2/07 and I have had spotting for five days 6/7 to 6/12 very dark to pink only I did not even need to wear a panty liner it was so light, increased appetite, metal taste in mouth ( like blood in my mouth) swollen tender bb's, insomnia, cramping like I am getting my AF but it never came, sense of smell is different, had sore throat on 6/6, Headaches which turned into migrains. I went to the doc. tonight and took a urine test which came back negative. I am so confused I don't know what is going on. If you have any info. or advice that an help me. I would really appreciate it. Thank you in advance. Pregnancy counters say that I am 8 or 9 weeks pregnant.
