nearly 5wks pregnant

Morning everyone could I ask people advise if that's ok. I'm nearly 5wks pregnant I've had morning sickness once and  I've been getting sharpe pains like I'm going to come on my period. Is this normal? I've not had a baby for 14 year, so not sure if I should be worried.  But I'm a little worried I'm trying not to be but it's hard because soon as the pain starts I think something is wrong it's been on and off for 2days now any advise would be greatful many thanks 😊
