cramps during pregnancy

hello moms, i am 15 weeks pregnant and recently detected na low placenta position si baby. i was advised to bed rest by my ob (more than 2weeks bedrest nako as of now) but almost every daw I felt dysmenorhea cramps, is that normal or something i should worry about? there are days na parang my brown spot sa panty ko but just one or two small dot and im very worried if its alarming or not need to stress out. please help me mommies esp those who had experience this situation. thank u so much! stay safe everyone! #pregnancy #advicepls #theasianparentph #cramps #lowplacenta
