His brain isn’t all that’s coming along; she’s also growing other integral organs, such as a heart and kidneys. In fact, he likely has a heart rateof about 100 beats per minute at this point. Additionally, your baby may be developing a tongue, arms and legs.
Toward the end of your seventh week, your child is nearly double the length he was at the beginning, reaching roughly 13 millimeters, with the head making up the majority of the volume.
Even though your baby is no bigger than a berry at seven weeks, you may begin to feel pressure on your bladder. This isn’t only due to your expanding uterus, but also an increase in a hormone called human chorionic gonadotropin (hCG), which helps to get blood flowing to yourpelvis. This is a good thing, because blood flow stimulation allows you to better get rid of waste, and hCG plays an integral role in placenta development—so just try to remember that the next time you’re racing to the bathroom.
You may also keep in mind that some women experience alleviation in their constant need to go once they enter their second trimester. But it also may reappear toward the end of your pregnancy when your little one settles down into your pelvis, leaving not much space for your bladder.
What’s important to remember is that even though your urge to urinate may seem intense and never-ending at times, don’t try to cut down on time spent in the bathroom by forgoing fluids. You and your baby need to remain hydrated, and a lack of fluids may cause a urinary tract infection, which is most unpleasant.
