High blood pressure?

At my 35 week midwife appointment my heart rate was consistently 108 or above but BP was normal. Went into hospital at 36 weeks with a bloody show and BP was 141/88 when I arrived and 139/92 when I left, said that my urine was fine and only been having mild headaches so they told me to rest and drink more. Is this considered high? Everything I’ve researched has suggested that this is considered high, and my mum had preeclampsia a few times so I was on low dose aspirin to prevent it but had to come off it due to negative side effects with my Antidepressants
