Need opinions!

Ok so I’m not really sure what to think. My last period was June 6-7th. We are trying to get pregnant so we had intercourse June 11, 14, and 15th. I was supposed to have my ovulation day June 18th. I then experienced light-moderate cramping June 28-30th thinking I was about to start my period but I’ve had nothing besides lots of cervical mucus. I am now 3 days late on my period but I took a test yesterday morning first thing (as of being 2 days late) and it came back negative. I use the Clearblue digital pregnancy test. I’m not sure what’s going on or if I should try a different test or if it will even matter. This would be our 3rd pregnancy so I’m not completely oblivious to how this works. I’m just usually very regular with my cycle so this scenario is different for me! Help a girl out please!
