Depression kicking in

So i posted almost a week ago pregnancy test with faint line, retested 4 more times within the week and got nearly the same results. Faint obvious lines. Today i have been so nauseated and in so much pain in my lower abdomen and lower back. Now im bleeding heavily like water just running.. I wanted to surprise my husband for Father's Day because we have been trying for exactly 2 years. Im so depressed at this moment.
