SORRY FOR THE PIC BUT I NEED HELP. Can implantation bleeding be a brown? I’m very confused. This week I’ve been so out of it. My boobs have been hurting but today they aren’t hurting as bad. Yesterday I was having a light brown discharge the cramping was very light. Today I have brown discharge and now I have some cramping and lower back pain. I took a pregnancy test this morning but it came back negative. I’m so confused. Also I have been having headaches and yesterday I felt like I was going to be sick but nothing came up.
