Headaches – Early Sign of Pregnancy

Posted on September 4th, 2008. Written by .

Headaches in pregnancy tend to occur most frequently in the first trimester. Hormone levels rise dramatically in early pregnancy, and can contribute to headaches. Changes in your blood circulation and blood volume during pregnancy can cause increased pressure on your blood vessels. This increase requires greater fluid intake to counteract dehydration, which can be another cause of headaches. Be sure to get at least 8 glasses of water a day.

Low blood sugar could also be the culprit, be sure to eat a healthy well balanced diet, with adequate protein and iron intakes. Avoid foods that can trigger a headache: like chocolate, MSG, cheese and spicy foods. Other possibilities are stress and anxiety or not getting enough rest. Try to take time each day to relax and make sure you get enough sleep.

Our data on September 4, 2008 shows that headaches are most common on 9 days past ovulation with 15.5% of pregnant women experiencing this symptom. Our data also shows that headaches is one of the top ten most common early signs of pregnancy. (View Top Ten Pregnancy Signs & Symptoms)

  1. Hey lam 23.my perold always seen every 19th of months,this month i missed it and now its 20th iam feeling abit fever and abit heachach slightly feel sick around 10:30am
    could it be an early sign?Reply to this comment

  2. Today is Feb 21, I had sex on Jan 20. So about a month ago, and he used a condom, and did not ejaculate in me. About a week after having sex, I got what I think was my period, but it was a week earlier than it was supposed to be, and it only lasted about 3 days, and was lighter than usual. When I got off my period, I had a clearish dishcharge, and I have had it constantly up until now. Somedays its very heavy, and other days not so much. Here lately I’ve been getting headaches, which I rarely ever get, ive been feelijg nauseated, but I havent puked yet, my allergies are crazy because the temps were very low and now its warm outside and the snow is melting, ive been nonstop hungry, im already a heavyset girl, but I feel very bloated, and my boobs only feel sore when I kind of press on them a little. I do not cry easily, and the littlest fights with someone will put me in tears, and Ive had mild cramping in my lower stomach area every now and then. I kmow the chances of me being pregnant are very low under the circumstances of my situation, but it is still possible, amd all of my symptoms are adding up. I also took a test about a week ago, but it was a cheap one and it was negaticve, but I dont think it was accurate. Do you think I’m pregnant?

  3. My period comes every other month. I had sex on my ovulation day and now I am 8 days late with symptons that could be pms or pregnant. I’ve been tired a lot more latley with headaches and very bad lower back pain. It feels like I’m about to start my period (the cramps and usual feeling) but nothing has came. I feel a litte nauseas at times and am having gas which I never really have. I also noticed dark brown discharge the other morning and have been having constant discharge (always for me) I’m trying to wait till I test but would really appreciate some help and advice! :)

    Thanks
