Help?

I'm not sure I'm pregnant yet or not. I haven't taken a test yet because husband and I like to wait until I miss my period. I noticed something unusual about my boobs today. I noticed I have Montgomery's tubercles (for those who don't know, it's tiny bumps on your areolas. Google it) on my areolas. Its a new thing for me as I pay close attention to my boobs all the time. I should be 11DPO and am supposed to get my period on the 21-22 of this month. I also have headaches from hell, my boobs tingle sometimes (mostly at night), and I've been bloated with some diarrhea. Sorry if that's TMI... These aren't my usual PMS symptoms as my lower back hasn't been in as much pain as it's always been in. Do you think there's a possibility that I'll get my BFP this month? Don't say take a test as I've said I'm waiting until I miss my period so I don't get my hopes only to get a negative. We've been TTC since the end of October.
