Delayed BFP anyone?

So let me start by saying I'm not crazy.
Here is my pregnant history-
Pregnancy # 1 = still born son 24/12/10.
Pregnancy # 2 = healthy daughter 25/11/11.
Pregnancy # 3 = miscarriage at 9 weeks with D&c 30/1/14.

Following mc I still had HCG in my system til a pregnancy test came back negative on 20/2/14. On 26 feb, 27 days after d&c, I got my period. It is now 35 days later and I am POSITIVE I'm pregnant again despite all tests saying negative.
Cramping started 2.5 weeks ago plus now more symptoms.. The biggest one being the protruding stomach that has developed since the weekend. I'm a size 8/10 normally with a relatively flat stomach. I showed early with all pregnancies. #1 I had a tummy by 8 weeks. #2 by 6 weeks. #3 by 5 weeks.
I have "felt" pregnant for 2 weeks. Hard to explain. I know my body. I've been pregnant 3 times before. I know what it feels like. U could say its wishful thinking on the symptoms but where did this pot come from? And where is my period?

I have googled and people say they've had pregnancies with negatives but who knows if they are REAL people. Has ANYONE here had this? Or personally know someone who has?

personally I havent found out that I was pregnant until around 7 weeks (latest was 13 weeks).
we are TTC and im 10DPO and feel pregnant, so tested but BFN. (I have a hormonal imbalance, so I dont expect it to show up this early, but I had high hopes)
So fingers crossed AF stays away and I get a BFP in 2 weeks, and i can tell you that it happened for me!

The only way you're going to know for sure is to go and get a blood test done, good luck, I hope it's the result you're hoping for :hug:
