I'm 23+4 days pregnant I woke up this morning with a mild headache that came and went as it pleased thought nothing of it, now I've had a throbbing headache for about 5 hours now and a constant mild pain in my stomach it's early hours in the morning (4am) so can't call my midwife It's stopping me from been able to get any sleep, I can also feel my baby moving more than usual could this be a sign of something serious?
