I am about 9dpo and two days ago I was getting ready for bed and felt so nauseated. I thought a shower and laying down would help but I still felt it, even my husband said I didn't look well. Once I fell asleep I was fine and haven't felt it much since then. Yesterday I felt it coming so I drank some ginger ale to stop it before it started and I was fine all day. Today I was checking CM and there was some brown but I wouldn't even have noticed if I didn't check. I don't know if it is IB or not but would I have symptoms like nausea before implantation even occurred? Thanks in advance!
