Worried 😔

Okay so I am 20 days late for my period and I took a 4 pregnancy test 2 were positive 2 were negative. My husband a I think we are pregnant and are going to a doctor later today. But I went to the bathroom there was a little spot of blood  n my underwear. I know it's comman to spot during a pregnancy, but now I am thinking I'm not and feel like we got our hopes up for nothing. 😢
