Renee,
On my 3rd IVF, I POAS everyday after my trigger. It was completely negative for days. On 13dpo, I started having some brown staining which turned into pink spotting and then full on red flow. I called my RE and begged to quit taking my meds because it was obvious that I wasn't pregnant. They said absolutely not and I was totally pi$$ed off. The next morning, the bleeding was gone so I POAS for the heck of it. Would you believe it was positive?? I had to wait until 14dpo (9dp5dt) to even get a HINT of a positive?? How cruel is that?
Getting an early BFP is not common. That's why most pg tests say to wait until you've missed your period. Even the FRE early response say there's a percentage of PG women who will not get a positive until the day after a missed period. So, there's still hope!
Good luck and we're all pulling for you!!!!
