I had bleeding at 8 weeks for 2 days straight. Today I am 29 weeks pregnant with a baby girl. I went to the ER when I started to bleed and they confirmed my cervix was closed and HCG were still rising. They did an ultrasound and there was still a heartbeat. I was diagnosed with a subchorionic hemorrhage - which I guess is common. It cleared up on it's own a few weeks later - and I was fine and have been!
I would call your office and speak with whoever is on call....Just so that they are aware....They may want to see you, they may not. Like sweetangel said, some spotting is normal in pregnancy.......But I would call just to be on the safe side. Good luck.
This is from the American pregnancy association:
About 25-30% of pregnant women experience some type of spotting or bleeding in early pregnancy. This can be a result of many different factors including implantation bleeding, infection, cervical irritation, ectopic pregnancy or a threatened miscarriage. Many women who have this light bleeding go on to have normal pregnancies and healthy babies. About half of the women who experience some light bleeding will go on to have heavier bleeding that will ultimately result in miscarriage. Unfortunately there is no way to predict whether or not vaginal bleeding will progress to miscarriage. If you experience light bleeding that continues to get heavier, accompanied by painful cramping, back pain or stabbing pains, then you would want to seek medical attention right away.
If you experience some very slight spotting that then goes away, you would want to make sure to share this with your healthcare provider so that they are fully informed of everything you are experiencing in your pregnancy.
