7 weeks pregnant: Your baby is the size of a blueberry

As you progress with your pregnancy, your body experiences unexpected changes. During the seventh week of your pregnancy, you may experience physical changes like frequent backaches, weight gain and fluid retention. Though uncomfortable but these symptoms are completely normal and go away as your pregnancy progresses.
The embryo at seven weeks
At seven weeks, your baby is the size of a blueberry and your embryo measures about 0.51 inches, double of the last week.
Baby development

Brain
The basic sections of the brain that have developed by now, get divided into three main sections during this week.
Features
Your baby’s eyes, ears and nose begin to develop. The eyelids are formed but remain closed. Paddle like hands and feet also start forming.
Pregnancy symptoms at seven weeks
Weight gain
One of the most noticeable changes during pregnancy is weight gain. This weight is important for your overall health and for the development and nourishment of your baby. The additional weight will eventually go away as the baby is born. Eat nutritious food, do not eat junk and exercise regularly.
Backache
Backache is a common problem during pregnancy but it’s by this week only that it becomes evident.
What to do?
- Do simple stretching or yoga to release tension in the back and leg muscles.
- Get yourself a massage to relax and loosen the tight and sore back muscles.
- Try sleeping with a pillow between your bent knees to support your lower back.
Nausea
Morning sickness may get worse by this time. But do not worry as there are several ways to cope with it.
What to do?
- Some moms have claimed to feel better by having ginger and Vitamin B6.
- Avoid oily and spicy foods.
- Drink plenty of fluids if you are vomiting so that you do not get dehydrated.
Food cravings or aversions
You may feel the urge to eat some specific foods or not wanting to go anywhere near certain foods that were fine for you before. It’s okay to give in to your cravings and indulge in them happily.
Frequent urination
You may have this constant urge to urinate because your uterus has doubled in size and the blood flow in your pelvis has increased.
Skin problems
Breakouts happen due to hormonal changes in your body. Before using any cream or products, consult your doctor if they are safe to be used at this time.
Extra saliva
This happens due to the hormonal changes in your body. Sadly, you can do nothing about it but just gulp it down.
Mood swings
Because your hormones are out of whack, mood swings are an obvious thing to happen. It can also happen because you are still getting used to the idea of being pregnant, which can make you extra emotional.
Cramping or spotting
Cramping during the early pregnancy is completely normal. A lot is happening in your uterus making you feel plenty of cramps. The cervix is sensitive at this time so spotting after sex at seven weeks can happen.
These two symptoms are alarming and can be worrisome. If you experience too much cramping or heavy bleeding, you should immediately call your doctor.
Seven weeks pregnant belly
Have you been looking at your pregnant belly in the mirror and trying to fake one by pushing it out? Everyone does that and it's completely normal. Only mothers who are pregnant with twins should expect to have a visible belly by this time for others it's nothing but just bloating.
If you do not experience any symptoms
Every mother experiences pregnancy differently. If you are seven weeks pregnant and do not have any symptoms at all, consider yourself lucky. Some mothers think of this as a worrisome thing but it's not.
