Pregnancy does not take place until there are ovulation and fertilization. In the first two weeks after your previous menstruation, nothing has happened.
Your body has just finished its ordeal and is getting ready for another one then something happened.
Your matured ovary was fertilized and a new being is formed (embryo) at the ampula of your Fallopian tube. This formed being has no head or limbs but just like a ball. it undergoes a lot of changes before it reaches the uterus. so unless the woman had previously developed low back pain before pregnancy, otherwise there would be no pain at the low back this time.

In your uterus, your baby embeds itself at the wall of your uterus being connected with you through the umbilical cord. Your baby feeds through you through this umbilical cord.
What to expect in the first month of your pregnancy
In the first two weeks after your menstruation, no pregnancy has occurred.
In the third week, something is happening inside you- the zygote is formed once one of the racing sperms wins and attaches its head into the ovum, moving down in the Fallopian tube and undergoing cell division.
Embedding of the fetus is taking place in the uterus; You might experience some dropping of blood from your vagina but don’t worry this is your child embedding into your uterus for the mother there will be the formation of umbilicus and placenta for its feeding.
