Mild cramps may be seen in an early pregnancy and it may not be associated with spotting or bleeding, which we called as implantation bleed or implantation cramps. They usually occur 3 – 4 weeks after conception and it is a dull boring pain, which goes off after it is fine. But these cramps can be easily mistaken as premenstrual symptom and which follows a delayed period or they feel the same and they usually occur at the same time. Any people with abortions, difficult pregnancies or ectopic pregnancies, the reason of the cramp should be confirmed by ultrasound or further testing
