Help! lots of BFN's, no AF, some light spotting! now nothing~ Advice needed, getting worried!

[HappyHappyMama]

Hi ladies... I need some help, my hubby and I have been very blessed with 3 kiddos. this month has been a weird month for us, and I need a little help in trying to figure out whats going on with my body.

 with all three previous preg, I got a BFP right away, by using the 5 days before test. Iam never late, always 28 days, and have normal Af's lasting 4-5 days, starting off bright pink-red, ending brown...

 this month, we b'd on the tuesday, wednesday and thursday evening, before the 12th, I ovulated on the 12th.... having felt preg all month, I took a 5 days before test, 4 days before, and BFN. then the day I was due for AF, and got a BFN and here Iam 4 days late and yesterday I got a BFN I started spotting yesterday, very faintly light light bright pink streaks in my CM then it when to 2 spots of brown on my panties... all night I used nothing no pad or anything, woke up to a bit more spotting of brown & dark red not a lot at all and no cramping ( i thought with the increase that maybe AF was on her way ), we had a 2 hr car ride home, so I put a tampon in  I took it out when I got home, and it had a little tiny bit of brown blood on it... thats it... now when I pee and wipe, there is nothing.  Iam not sure whats going on.... I need some advice, should I be worried, Ive looked up belighted ovum, tubal pregnancy, and any other somthing it could be, and I dont really fit into any catagorie. they say that implantation occors 6-12 days but would I have not already implanted if I was indeed preggers and before AF was due .... leaving the spotting now, to not coinside with that? I ahve no clue whats going on, ( the only other day this month that we had sex was the 24th ( AF was due on the 28th) and iam getting a little worried that somthing might be wrong, again I have no heavey flow and absolutly no cramping...if anyone has any idea what I should be thinking or doing, or any concerns or advice please help me out here... thank you in advance:) I really appreciate all your replys and advice.... Iam really getting worried, my body is usually so predictable!

I don't have much advice b/c I came here to find an answer to the same question! AF was due today and is never late...I had brown spotting yesterday, which has never happened to me the day before AF. Then today more brown and a tiny bit of dark red, but certainly no flow. No cramping. We are TTC, but I haven't tested b/c I don't feel pregnant at all.

I know blighted ovum pregnancies typically start off looking like normal pregnancies. My first pregnancy was a blighted ovum, and I had no idea there was anything wrong until I was 7 weeks along and started bleeding.

I hope someone else will weigh in with an answer to why a reliable AF would suddenly be so scant and unusual. I am really wondering, too!

It's just a wait and see game.  Do you chart?  Do you know that you ovulated (OPKs?)? 

Any woman CAN have an anovulatory cycle, long cycle, late ovulation, light period or be pg with slow rising HCG levels for no appearant reason.  Even women who ALWAYS have a regular cycle.  (A missed period happened to me once.)  There's always those stories of women who didn't get their BFP til they were a week or more late.  (My sister is one of them.  She tested everyday and didn't get a BFP til AF was 10 days late and went on to have a healthy baby boy.) 

It depends on how concerned you are.  Personally, I would keep testing til a BFP or AF.  But, there's nothing wrong with going to see the doc and getting a blood test and getting checked. 

Let us know what you do.
