With another week in, it’s yet another week of pregnancy symptoms that you’ve got to face. But we’re guessing it’s nothing you can’t handle considering the nauseous phase you experienced in the 1st trimester.

Being 23 weeks pregnant, here are some signs and symptom that your body might be experiencing:

  • Swollen limbs. With the increased amount of built up body fluid, you might find yourself having a thicker set of limbs. With pregnant legs being one of the more common pregnancy symptoms at this stage of your pregnancy, you can counter it by taking more strolls to relieve the swelling. Most importantly, do drink more water to prevent water retention and this would help significantly with the swelling. Do however, watch out for unusual levels of swelling as that might be an indication of pregnancy complication which must be looked at immediately. Other than that, keep calm and walk on to keep those limbs swell-free.

  • Backaches. Yes, it was here last week and it’s not about to leave this week. Backaches in common theme from here on as the little one is growing continually.

The weightlessness of swimming or even dipping in the pool helps with the pressure and strain on your back. So find the nearest swimming complex and dip yourself in a pool of much needed relief.
  • Swollen gums. What has pregnancy got to do with my mouth you ask. Yes, unfortunately, pregnancy has a way to mess with our body and it has found its way in our mouth. Swollen and even bloody gums are not uncommon when it comes to pregnancy due to the increase in blood flow coupled with, yes, you guessed it – pregnancy hormones! With our gums being more sensitive at this point, it would be of great relief if you changed your toothbrush to one with a soft bristle.
