Is Aspirin okay in pregnancy?

Chloe • Mummy To Cayde 💙 And Darcy 💜
Been told to take 75mg of aspirin since 12weeks (currently 26 weeks) which I have been but I just brought a new pack and they aren't dissolvable plus they sate on there not to take when pregnant? Can't get hold of my midwife. shall I continue on taking them? Advise pleaseeee 😊
