Firstly, you should stop worrying unnecessarily. Pregnancy
is a natural process, it is not a disease. You are lucky that you do not have that severe morning sickness
which so many others have at this stage. You should consult your doctor and get advice regarding your cramps; they could be the usual ones as the uterus
enlarges or caused by your constipation
. Weakness is a normal part of pregnancy, especially, in early stages.Stool softeners are not advisable in pregnancy as they tend to cause uterine irritability. Do not research yourself as this is going to adversely affect your baby. Instead go for some book reading on baby care. Please get further instructions from your doctor. Take care.
