Guys i checked my period calendar

Something is wrong ! I mean 144 days!

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.

Question! If I'm just ovulating today and my period is supposed to be due January 4th. Will I have my period on time?

Losing my mucus plug with period type pain.just wondering is this normal at this stage or could be the start of something? 37 weeks today.

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 :)
