Had my 20 weeks scan today and was told my placenta was quite low so am booked for another scan at 34 weeks to see if its moved. Midwife said not to have sex. I've had a read on here and a general google and it sounds like potentially this could be quite dangerous. I wasn't told to avoid heavy lifting or anything. I have horses and they can drag me around a little at the moment as we go through the grassy field - is it safe for me to handle them?? Exactly how cautious should i be at the moment??
