Today i started getting reasonable stomach pains as well Is this suggestive of anything? does it mean the embryo hasn t taken? I have my blood test to confirm pregnany on day ten to come with thanks [/INST] Hello and welcome to Chat Doctor The tingling sensation in the groin and stomach pain does not indicate success or failure of embryo replacement. These two symptoms have some other pathology. Stomach pain can occur due to various causes- ingestion, muscular pain, spasm of stomach muscles. Infact it is due to the organ which lies at the point of pain. Abdomen is a big area and many organs are present in the abdominal cavity like liver, pancreas, spleen, intestine, etc. You need to visit the GP to know the exact cause. You may need an ultrasound abdomen. Regarding the tingling sensation in the groin, it could be due to nerve compression while performing the embryo replacement. If it is not relieved in few days please consult your GP for complete examination. Thanks and take care Chat Doctor.  </s>
