Confused

So I started spotting 11/22/18 and it only happened for 2 days not my period as I get really bad cramps to the point where I can’t get up . This was literally spots , red pink and then brown . I took a test and it was a faint positive but you could definitely see it . Then I waited a few more days and had more spotting for one day . This was 11/29 . Yesterday 12/11 I took another test and again faint . Today I went to have a blood test and it was negative. I have been feeling nauseous. Threw up this morning . Some pelvic cramps , my breast hurt , and loss of appetite. I don’t know what to do . We have been trying for 2 years .

11/23

12/11
