Short Luteal Phase?

I've just started temping because I believe that the reason I haven't had a BFP yet, after 20 months, is because I believe I may have a Luteal Phase Defect.

So I keep feeling these lil sharp pains on my right side. You do get pains like that before you start your period right.? Remember I had that dark brown spotting for a few hours last month on the 22. My period suppose to start today.

So I thought I was starting my period. I woke up this morning with tiny cramps nothing major. I then had to use the bathroom and I was spotting. It has since went away and I hope it stay away. My last period was Dec. 28 and I should've came on Jan. 25th but nothing.

I Have A Question. Is This Positive Or What Is This? I Took This Way Before Ovulation And After My Light Period From My Miscarriage.. Been Trying To Concieve After I Got This Too. Waiting To Miss My Period Though. Then I'll Take Another One If So. Help??

I gotta question could I be pregnant and have 2 1/2 day period because I think i got pregnant on Nov 26 and had implantation bleeding on Dec 11 because I'm usually on my period for at least 4 days but mostly 5 or 6 which my full period was Nov 11 for 5 days ?? but in dec only 2 1/2 days it's kinda confusing really im excited about my Dr visit feb19 to know for sure :)
