Ok so whats happening??

I definately had to hit my fertile days...i BD the nights before and after i had a positive OPK. AF is due tomorrow...so we will see whats going to happen. I have had a neg hpt on 10dpo and 11 dpo. Buuuuut the wierd thing is that a few days ago i had terrible pains in the sides of my . When ever you put light pressure on them they hurt. It happened like 2 days and stopped about 2 days ago. I never get that when i start...the only soreness i get is rare and its usually just the nipple and very barely sore. Also i swear that the veins of my s are more profound...not really popping out just alot bluer. I had some mild cramping yesterday but absolutely nothing today. Usually i break out real bad before a period too and i havent really done that. So what could be happening? I am really looking for a BFP. Im hoping and praying i get one though by the looks of it i doubt it. Please send lots of baby dust.
