Cycle buddies, due 12/06?

Jessica
So this cycle has been different for me already. I'm only 6DPO, but with my daughter I got my BFP at 9DPO. So I'm very anxiously waiting, but I don't plan on testing until the day before (12/5, AND my birthday), or the day of. 
I got my pregnancy confirmed with my daughter on my birthday 4 years ago, so it'll be insane if it happens again with number 2! 
As far as my symptoms, my body is highly sensitive to any hormonal changes, and I've already been feeling.. "Off". I've had migraines (but I have chronic migraine so I'm not sure), yellow, creamy CM, hot/cold flashes, light, constant cramping, heartburn after I eat, VERY gassy (unusual for me), insomnia (again not like me at all, I sleep like a log), along with constant lower backaches, and this morning I woke up with blue veins on my lower stomach and left breast, which I have NEVER experienced before. I also woke up 4-5 times last night to pee, which is very unlike me, as well. 
I know "most symptoms don't start until 3 weeks ish", but in my case, it doesn't. I know my body really well and my body is so sensitive to any change in my hormone levels. With my daughter, I knew the second implantation occurred, and even the doctors didn't believe me because my test was so light. So, I just go with what I feel and what my body tells me. 
Sorry for the novel, I just needed to share because I'm so anxious it's killing me, and was wondering if anyone else out there has felt anything! 😊
