Symptoms which u are telling are very much related with pregnancy
But u said that ur stomach cramps
have not stopped which is matter of concern as it might be. Threatened abortion
U shoul visit ur gynaec.
It might be case of GERD
Ur doctor would prescribe u with some anti emetics and anti cramps medicine.
Some degree of contractions are normal with pregnancy ,but if not relieved on rest or interfering with sleep can land in to abortion.
So p,z see ur gynaec. Byeeee.
