Dull aches, some slight bloody mucus & terrified!

Ok I've been having dull aches now for about a week (since I found out) I'm 9 week + 4 and felt a kind of trickle down there  I ran to the bathroom and found brown bloody mucus when I wiped ! I am terrified I rang the hospital midwives who have advised me I should go to the A&E (E.R) to ease my mind! I've rang my DH who is 100 miles away with work travelling home and I now have an anxious wait till he gets back and in the waiting room! I feel sick to my stomach my mouth is dry and am praying it's good news! From reading about this type of bleed it's apparently common and often nothing to worry about! I am absolutely terrified of getting in there and saying those dreaded words ?? has anyone else experienced this before? This is my 3rd pregnancy and have never had anything like this!! I think I'm even more worried because when my GP asked have I ever had a loss before to which I replied, a suspected one before my first baby, but I can't confirm it 100% she started talking about pretty much everyone will experience it in a life time so the midwives might not see you before 12 weeks ! This has echoed in my ears, it's not something I wanted to hear no matter how true it is! I just can't stop panicking and getting upset ???
