Experiencing constant headaches and a loss of appetite during the 7th week of pregnancy is not uncommon. These symptoms can be attributed to hormonal changes, increased blood volume, or other factors. To manage constant headaches, try relaxation techniques such as deep breathing exercises or gentle massages. Applying a cold or warm compress to your head may also provide relief. It's important to stay hydrated and maintain a balanced diet despite the loss of appetite. Eating small, frequent meals that include nutrient-rich foods like fruits, vegetables, lean proteins, and whole grains can help alleviate symptoms. If these symptoms persist or worsen, consult your healthcare provider for further evaluation and guidance.
