Your baby at 25 weeks

You might feel the occasional rhythmic hiccup.

Your body at 25 weeks

Your face, hands and feet may swell, usually from water retention.

Heartburn, burping, bloating and feeling full quickly are common.

Feet up when you can, and comfy wide shoes are worth every penny.

Your to-do list at 25 weeks

  • Tell your midwife about swelling so they can check your blood pressure.
  • Call your midwife, GP or NHS 111 straight away if you have a bad headache, problems with your vision or pain just below your ribs, as these can be signs of pre-eclampsia.

If you’re trying to conceive (TTC), you probably know that there are certain foods and nutrients that become especially important once you’re pregnant. But nutrition plays a vital role even when trying to conceive, much like laying a strong foundation before constructing a house.

Certain nutrients create that foundation by supporting egg and sperm health (yes, nutrition matters for both partners), hormone balance and creating a hospitable environment for a fertilized egg to implant. In fact, studies show that certain nutrients can help increase fertility and improve success rates for both natural conception and fertility treatments.

‍

In other words, nutrition is a key player in the TTC journey, but getting the right nutrients in the right quantities can be tricky. That’s where supplements come in. Just as you’d take a multivitamin to fill in nutritional gaps for optimal health, fertility supplements can give you that extra nutrient boost.
