Just had my 8 week ultrasound, and heart beat looked good, and size was right on track! But my doctor did see I have an implantation bleed, or subchorionic hemorrhage. It only measured 1 cm, and she said it was in an okay position, i.e. not above my cervix. But she really didn't tell me much else...she said we had to abstain from intercourse until they do another ultrasound in 2 weeks, but didn't say anything about resting otherwise....should I also be taking it easy and not doing light exercise? I usually walk about 2 miles in the evening, and do some strength exercises similar to yoga....but if I SHOULD abstain even from these for a couple weeks, I obviously will....I don't want to jeopardize my little one! What would people's advice be?? Have your doctors asked you to abstain from more than just intercourse?
