My saga Continues

[psychobear]

My dr told me on monday that although my hcg has only gone up a little bit and that it could be normal for me. He says that I just have to take a serial reading of my hcg level and then figure out if I have miscarried based on that. I had a blood test done that day and will get another on thursday to see where we are at. I am still spotting/bleeding. It is sometimes dark coloured and sometimes bright red. It still isn't soaking through pads and I have some lower back discomfort but not really cramping per se. My question is to those who have gone through this how much bleeding is still "normal" and how long can it last in viable pregnancies? So far it has been going on for almost a week. I think I have researched this subject to death and can never find any decent answers. I am just so mentally drained from the wait to find out what is happening to my body/baby. I understand that everyone is individual but I am just looking for some anecdotal information from those of you who have been there.
PS. All you women who have gone through this multiple times must have the strength and spirit of a warrior. It is the hardest thing I have ever dealt with and I have gone through a few traumas in my time
Further info: I had a u/s last week and was told that since I was only about 5-6 wks along there were no signs that could tell me either way if everything was ok---so no fetal heartbeat but the yolk sack was present and looked fine. My first blood test showed a hcg level of 5200ish the one taken two days later was just over 5800. I had another drawn after another two days and then will do it again tomorrow. I then go to my Dr. on Friday to get the news. I am just soooo tired of going between hope and despair. It is always the unknown that frightens us most. Thank god for my husband. He has been so amazingly sweet and gentle with me.
