Preeclampsia

If you’ve had preeclampsia more than once, can you tell me how effective is baby aspirin? I had severe preeclampsia with my last pregnancy and I’m currently pregnant (17 weeks) and my midwife prescribed me some baby aspirin and I’m curious to know how likely are you to carry full term and if the baby aspirin work? I had my daughter at 30 weeks and I’m not trying to go down that road again.. it was very painful. 😔
