Paranoid (TMI)

I went to my appointment this morning and I told my doctor I was having some brpwn spotting. I'm 9 weeks. I don't remember having this much spotting with first pregnancy and it's a bit worrying. My doctor said it's normal but they want me to take it easy and refrain from any sexual activity until I reach the 12 week mark. I do have a two year that I'm always chasing around and I was told not to pick him up nor carry him anymore. I'm still having some spotting. Still brown. They said if it becomes really red then there's something wrong. I have had this happen already 3 times this pregnancy. I'm just hoping it clears up. I'm so worried.
