At one month pregnant, you have actually only been pregnant for about two weeks. This is because the number of weeks in your pregnancy starts from the date of your last menstrual cycle instead of the actual date of ovulation or conception. According to the Office on Women's Health, symptoms of pregnancy can start as early as one week after conception.
During the fourth week of pregnancy, you will notice your period is absent. However, you may notice slight spotting approximately six to 12 days after conception. This spotting is called implantation bleeding, according to the American Pregnancy Association. Implantation bleeding may occur around the same time as when you expect your period. Around the time of your missed period, you can take a pregnancy test, which may come back positive; however, if the test is negative and you believe you are pregnant, either visit your doctor or wait about a week and take a new test.
Aches and Pains
Pregnancy, even at one month, causes aches and pains. Your breasts may be tender and slightly swollen, and you may have a headache or backache. When you add pregnancy-related fatigue in with these aches and pains, you may feel even worse.
At one month into your pregnancy, you may notice that you are making more trips to the bathroom. You will have to urinate more often. If you experience morning sickness, you may have to make trips to the bathroom to vomit. Some women may also experience constipation during the first month of pregnancy and beyond.
Food Cravings and Aversions
Food cravings and aversions are common one month into your pregnancy. Foods you didn't like before getting pregnant may now appeal to you. Foods you once liked may make you sick. These cravings and aversions are normal; however, if you begin to crave non-food items, such as clay or dirt, contact your doctor immediately, as these are signs of a nutrient deficiency.
