When to call your midwife or maternity unit

NHS advice is to call if you think you're in labour and your contractions are coming every 5 minutes or more often. They'll talk you through whether to stay at home a little longer or come in.

Call straight away, even in the middle of the night, if

  • any contraction lasts longer than 2 minutes
  • you're having 6 or more contractions every 10 minutes
  • your waters break
  • you have any vaginal bleeding
  • your baby is moving less than usual, or the pattern of movements changes
  • you're less than 37 weeks pregnant and think you might be in labour

Call 999 if you think your baby is coming now and you have a strong urge to push. If you can't get through to your midwife or maternity unit, call 111.

How to time a contraction

Start timing when you feel the tightening begin and stop when it fades away. The gap is measured from the start of one contraction to the start of the next. Early contractions are often irregular, so keep going for an hour or so to see a pattern.

A note on your baby's movements

You don't need to count kicks. What matters is getting to know your baby's usual pattern. If movements slow down, stop or change, call your maternity unit straight away. Don't wait until the next day.

More for the big day

This timer is a guide only. Always follow the advice of your own midwife or maternity unit, and call them if you're worried about anything, even if it isn't on this list.

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.
