Cramping is always a concern during pregnancy, however it is not always as sinister as it may first appear. Obviously, a woman who experiences pain, especially during the first trimester, will be concerned that she is about to miscarry. Just as with morning sickness, implantation cramps are no cause for concern and indeed, could be seen as reason for celebration. If the woman has been trying to conceive and is under the care of a physician, she may report the pain. The doctor, suspecting pregnancy and potential for miscarriage, may or may not suggest an ultrasound but this is unlikely unless the patient has a history of miscarriage. Even pain accompanied by bleeding can be attributed to implantation cramps. When conception takes place, the body's production of progesterone and estrogen focuses on preparing a bed of blood vessels for the implantation of the zygote.
