I know how terrifying any pinch or pain in the stomach feels when you are hoping to get pregnant, every little sensation makes the heart race. Mild cramping is common, but to put your mind at peace, it's best to wait for your period date and take a test.
Yes, mild cramping is quite common as the uterus prepares itself, but don't assume anything. Wait for your missed period to test. If the pain gets intense or you feel dizzy, don't wait—go see your gynac right away.
Sometimes mild cramping happens due to the uterus stretching early on. Try to stay hydrated and eat light, balanced meals. But if the pain is severe or doesn't go away, please call your gynac.
Please be very careful with lower abdominal pain. I had severe cramping early on which turned out to be a complication, so I always advise getting a doctor's opinion. If the pain is sharp or you see any bleeding, go to the clinic immediately.
It can be a very early sign like implantation cramping or even just normal period cramps. However, if the pain is sharp, on one side, or accompanied by spotting, please consult your doctor immediately to rule out any issues.
