AF due 4-4-15 but late

Af was due 4-4-15 however no signs as of 4-7-15. However major acne breakout ewcm to watery mucus sore breasts queasy but no vomiting vivid dreams nightly yet a negative hpt. Went to doctor and also negative urine test. Anyone due same time and missed af. I'm thinking of going for a blood pregnancy test. Doc said I have all the signs of early pregnancy but maybe not enough hcg to detect in urine. Help
