Sooo long story short, I went out with a friend and we had sex... like 5 times on the 7th. Which I didn't know was the end if my ovulation window, so not even 16 hours later I took plan B. And my period was due today, and nothing but light cramping. I know plan B can delay your period but I was wondering if it would be worth buying a test?

My boobs are kind of soar and my back hurts but thats all normal with my periods anyways? Thoughts? Advice? Thanks in advance 😅💜
