Hi Lilangel,
'Spotting' is fairly common when pregnant and if the blood is darkish brown in colour, then there's generally no need to worry. A nurse told me to only worry if loosing more than a teaspoon full of blood into a sanitary towell.
I miscarried a week ago at 8wks. My symptoms prior to the event were a really bloated stomach, loss of feeling nauseous (I had been feeling sickish for 4 weeks), started bleeding & the blood got more red in colour over 2days & had clots in it. A scan at hospital confirmed I was about to miscarry.
If you are in any doubts, either call your early prgnancy unit at hospital, or just turn up & they can examine you and give you a scan if necessary.
I hope this e-mail is of some help to you, and my fingers are crossed for you.
