Before going into the description of "Sharp Pain" it must be clear that a flight consists of three major phases i.e, takeoff/climb, cruise and descent/landing. All the three phases require differernt PRESSURIZATION SEQUENCES to be maintained inside the cabin to maintain the atmospheric pressure conditions that are almost indentical to that of the sea level, normally 14.7 Psi (however the pressure inside the cabin is slightly lower thatn this value). This "Sharp Pain" in the forehead is associated with these pressurization sequences. The pressurization sequence starts as soon as the aircraft starts running on the runway and the cabin pressure is actually increased (as if the aircraft is diving down below the sea level !!!!). This increase in cabin pressure is necessary to counter the effect of reduced atmospheric pressure at higher altitudes. As a result of this PRE-PRESSURIZATION, a sort of pain is felt in the forehead while the aircraft is still on the ground during takeoff phase !!!! Similar sort of experince is witnessed during the descent phase when the ears start aching because of the increase in cabin pressure as the altitude decreases.
In this answer I have assumed that the reader is aware of the concept of CABIN PRESSURIZATION of an aircraft. If this concept isn't clear I would be more than happy to explain it in order to better understand why PRESSURIZATION is necessary which ultimately has to do a lot with the Sharp Pain phenomenon !!!!!!

Is lower abdominal pain normal during the first 4 weeks of pregnancy?
It depends on the type of pain. Is it a cramping dull kind of pain like you normally have during your periods or is it a sharp kind of pain that goes on and off? If it is the latter, I suggest you check with your doctor straight away because I had that at 4 weeks for a few days and by the 7th week had miscarried.
