You can drink 80ozs of water a day or more. That will help. Brown blood is old blood and quite normal. Hang in there! Congratulations
I had the spotting part for about a day I think it was pinkish, pain wise I use a hot water bottle and get into bed, paracetamol doesn't seem to do a lot :( I just don't have the bottle too hot and make sure I have clothing on plus a cover on the bottle, only thing that helps me. Congratulations on your pregnancy :)
