Missed period, boobs not sore

The Little Mermaid

AF is two days late. I haven’t had any intercourse without a condom but my partner still ejaculates in me with the condom on. Normally my breasts are sore before period comes but my breast’s have not been sore at all this cycle. My cycles are usually 24-26 days, and in May it came twice. Sounds more like irregular cycles or pregnancy?
