Hi Jo
There are a number of things that can cause bleeding in pregnancy. If the blood on the toilet paper is pink rather than red then this is of no real concern as it is usually caused by trauma which can be the result of having. Cramping is also not unusual at this point in pregnancy and is usually caused by stretching of ligaments and muscles due to your growing uterus. However whenever you have bleeding and cramping together it is always worth getting things checked out.
