Sore breasts; pregnancy or pms?

Since 1 dpo my breasts, on the sides, have been extremely sore and swollen. My nipples have been sore to the touch as well. Also, since going off the pill in January I’ve been spotting significantly 1 week prior to AF.

Today, I’m 10 dpo and haven’t had any spotting and aside from the sore breasts haven’t experienced much of my other PMS symptoms (mood swings, cramps, bloating).

Any thoughts?

Hubby and I did the deed on the day of ovulation this past month and have been trying for 3.
