As difficult as headaches in pregnancy can be to tolerate, remember that this is a temporary condition and they diminish considerably by the end of the third or fourth month.
Most women don't experience headaches past that point, unless other medical conditions are triggering them.
Pregnancy Headaches
Headaches in early pregnancy are a common symptom and begin at about the 6th week. A quick nap can help diminish headaches in pregnancy.
Preeclampsia or toxemia can begin with headache and can be dangerous to a pregnant woman. If you are pregnant and have this symptom, be sure to call your health care provider immediately.
Spotting
Spotting is a common symptom in pregnancy. Some women report what seems to be a short light period before the onset of other symptoms. This may be implantation bleeding and not a monthly period at all (when the egg implants itself into the lining of the uterus). If you are pregnant and you experience spotting check in with your doctor as spotting is also an indicator of miscarriage in early pregnancy.
Light Headedness
Some pregnant women experience actual fainting and light headedness. Again, this is usually not an issue past the fourth month of pregnancy.
Constipation
Hormonal changes can affect the digestive system and cause constipation. Drinking plenty of water and exercising can help. A pregnant woman should ask her doctor for recommended exercises while pregnant.
Heartburn
Heartburn can be a symptom in months 1-9. In months 1-4, heartburn is caused by hormonal changes. In months 5-9, the baby can cause pressure on a pregnant woman's organs. Eating frequent smaller meals and remaining in an upright position at least an hour after eating can help.
In pregnancy, with some fathers-to-be, it is difficult for them to understand the life that is within their mate. It is beneficial for the mother and father to be at the first ultrasound together as it seems to help fathers-to-be form a mental picture when they see movement of their baby on the ultrasound screen. Anticipation soon grows!
In Conclusion
By the end of the fourth month of pregnancy, most of these pregnancy symptoms subside and the elation and joy overcome most any mother to be. Energy levels return to normal as does the desire for food.
Headaches in early pregnancy are a common symptom and begin at about the 6th week. A quick nap can help diminish headaches in pregnancy.
