A lot of women have slight spotting in the beginning of pregnancy. Brown blood is old blood which is a good sign that it is not bright red. Do as your doctor recommended, but remember, even at 5 weeks it may still be too early to see much. Most of the time a heartbeat cannot be seen until 6-8 weeks. Good luck to you and keep us posted on what happens next week.
congratulations on your pregnancy
probably you heard this before but everybody said that if its brown its old blood, so you shouldn't be very worry about it, but I think its good idea as your doctor sugested to take it easy until you have your next appointment. I suppose the reason your doctor is not asking you to go now its because he won't be able to see anything yet , its to early. At 5 weeks he should be able to see at least the sac. The best of luck gemma. Looking forward to hear your good news
