I have no one I could talk to so why not here

I got my period on May 14, and it ended on May 19. I usually use condoms, but on May 22, I had unprotected sex it was a one-time, in-the-moment decision. I believe I started ovulating around May 27, with ovulation likely peaking around June 1st. Since then, I’ve had mild cramping in my lower belly mostly in the middle or on the left side, sometimes on the right in waves. Between June 1 and June 8, I had strong nausea, especially in the mornings. I was extremely tired, taking 5-hour naps daily on top of getting 8 hours of sleep at night and still feeling exhausted. Very bad mood swings!

Lately, I’ve been urinating frequently, even after just small sips of water. I’ve also had bad heartburn, hot flashes, sensitive nipples, and frequent headaches. On June 9th I noticed very light pink spotting — only when I wiped twice, then it stopped completely and hasn’t returned.

My period is due on June 15, so now I’m just watching for any more signs. I'm hoping I am! Just scared and nervous planing to test on the 16th
