Missed period

I had unprotected sex on May 17 & then got my regular period on May 20th-25th.

My period was due on June 22nd & now it’s 9 days late, so I didn’t have a period at all in June.

I took a pregnancy test on the 5th late day and it was negative. I’ve been having light cramps off and on for the last few days and just been sluggish (But I also have been staying up late due to being anxious/worried about this.)

I plan on taking another test within the next couple of days but I do have an appointment at a Planned Parenthood just in case. Thoughts?
