If someone is or thinks they're preggers...

Could they still do exercise...let's say...kickboxing? Let's say, they want to lose weight and kickboxing is a great way, right but they think they're preggers. Could they still do it anyway even without knowing for sure?

You need to take a pregnancy test before doing that kind of exercise. Walking and stuff is good for you when you're pregnant, but you shouldn't do kickboxing..no.

If you would be considered high risk (diabetes, thyroid disorder, HIV) then definitely not. You could do high impact exercise for up to four months.

no, you shouldnt
loosing weight could harm the baby, or worse
you need to put on extra weight when your pregnant
thats how the baby survives
first you need to find out if your pregnant
to find out if your pregnant take a pregnancy test 2-3 weeks after you had sex
(any sooner and the results won’t be accurate)
in the morning with your first pee is the best time
and take it when your period is due
alternatively, see a doctor for a blood test
this will both let you find out quicker and give you more accurate results
then see a doctor to dicuss your options
also talk to your mum

You only need to consume 200 more calories per day during pregnancy if you are already healthy. If you are overweight/obese then studies show you should not gain anymore weight.
