If you have sudden bleeding at 7 weeks of pregnancy without abdominal pain, you should consider the possibility of pre-eclampsia miscarriage and go to the hospital in time. If necessary, a hormone level test is needed to avoid low progesterone levels due to luteal insufficiency. It is also common to have an ectopic pregnancy, as the gestational sac may rupture when it reaches a certain level of development, and if the rupture is small, there may be vaginal bleeding without abdominal pain, but of short duration, followed by severe abdominal pain. Strict bed rest, avoiding excessive exercise, overexertion and staying up late are necessary.
