I have question need some advice please!!!?

My last period was January 27th so I was expecting my period the 24th of the month at the latest the 25th! I took a family dollar brand pregnancy test on the 24th and I got a BFN! I took the EPT test yesterday(the one that can predict 5 days sooner) and another BFN! the only symptoms that I had was sore (especially at bed time), frequent urination,I have creamy CM (sorry if TMI),occasional pressure in my lower abdomen and lower back pain thinking that AF was approaching but wasnt!!! I was going to schedule a blood test but I was going to wait atleast until Monday! So I can say that I am 5 days late. What does everyone else think I should do? Do you think that I am pregnant but I am not producing enough hormones yet? Or give it some time because some people dont get a BFP until 10 days after AF was due? thank you everyone in advance all your advice will be deeply appreciated!!
