Late Period

It’s been five days overdue since my period was supposed to come. I took two tests this morning and they both came back negative. My last cycle was Jan. 27th and it is now March 1st. I’ve had unprotected sex with my boyfriend DURING my period but now I have no period and it’s getting pretty late so I’m getting skeptical. Is it too early to test? Should I wait and test again next week? Or should I see my doc? (I’ve also had very detailed dreams about me being pregnant and sometimes my stomach hurts but nothing major. My breasts have also gotten fuller/bigger. I think I have some symptoms but not a hole lot.)
