What’s going on?

I was supposed to get my period on may 18th and I have yet to get it. I’ve taken multiple urine pregnancy tests which have all been negative and most recently a blood test yesterday which was negative. My periods are always regular so I’m just really confused. Also since I’m not pregnant right now, can I still get pregnant during this time frame where I’ve missed my period? We’re still trying but don’t know if it will do anything.
