So this morning I felt my breast more pain than yesterday only when I feel it in the middle or where my armpits are but I also went to check and my left breast looks bigger than the other and I can't tell the nipples getting dark yet but it's sensitive more than the breast so I was wondering am I because I'm confused my cervical mucus increased but not much it's just watery and I did have symptoms two days in a row like gas mostly, backaches, headache (slight one) Could I be pregnant?

Also I'm confused because I'm in my early luteal phase but my temperature decreased instead of increasing. It went to 97.9 but I don't know if I am because I'm having symptoms on my 2dpo.

If you have been having sex you could be pregnant. Missed period?

The changes that you are experiencing can be due to ovulation itself. As for size, it is not uncommon for women to have breasts of different sizes. Sometimes it is a very subtle difference, sometimes more obvious. At two dpo (days past ovulation), if you did become pregnant, the fertilized egg would still be making its way to the uterus (in most cases) and implantation would not have occurred yet.

How long have you been temping and charting? It can take a few months to see a pattern, and if you have off cycles, it can be difficult to follow. With the signs you have, continue to keep track this cycle to see if you get that slight rise. You could be off by just a couple of days. Remember, once you see a rise, ovulation has already occurred, so you aren't waiting for the rise to have intercourse, you are noting a pattern, in addition to changes in cervical mucous, to gauge when you are most likely to ovulate, and want to engage in intercourse over the several days prior to when you suspect ovulation to occur and a couple of days after as well.
