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.

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 :)

Guys if I was looking at a place to rent on Craigslist and I go to click on the ad again and this pops up does that mean it's a scam?? I need to know because my boyfriend and I have been talking to the person !!

Having some pretty intense constant lower back pain and maybe super light contractions. But can't tell because the back pain is way over powering contractions so I'm walking around my room to see if they get worse.

all pregnant women complain we're pregnant we have every right to complain doesn't matter if your early in pregnancy or late in pregnancy I complained everyday of my entire pregnancy because it really sucked for me and I'm only about to be 39 weeks so I'm gonna complain even more
