Confused

I’ve been getting light cramps when I’ve been lying down for a while. Some of the cramps feel like AF cramps and I have had some light pelvic pain as well that I can best describe as feeling like ovulation pain. AF is due on Jan. 14 and I ovulated on Dec. 31 (used OPKs).

I don’t want to get my hopes up. Last month, I was almost positive I was pregnant. I had every symptom and really “felt” like it was my month. This month I’ve just felt kind of blah. My boobs are really veiny and sore. Other than the light cramps, veiny/sore boobs I haven’t really had any symptoms.

Just wondering if anyone has experienced anything similar. Any insight is appreciated.
