If you are 32 days pregnant with vague pain in the stomach, the following clinical causes are common: first, contraction of the smooth muscle of the uterus caused by progesterone deficiency, resulting in symptoms of pre-eclampsia, which requires monitoring of blood HCG and progesterone for further understanding before appropriate treatment is given, and bed rest is recommended. The second one is vague pain in the lower abdomen caused by ectopic pregnancy. If the fertilized egg is locally implanted in the fallopian tube on the 32nd day of pregnancy, it will cause local vague pain, and the blood HCG should be monitored. It is advisable to be hospitalized for observation and to continue to monitor the blood HCG and, if necessary, to know the location of the gestational sac by ultrasound examination in order to make the appropriate diagnosis and then to deal with it.
