Placental insufficiency in following pregnancy?

Chloe • C.Millard✨

I had placental insufficiency with my son and we didn’t know till 34 weeks, I was induced at 35 & he weighed 3lb 13oz, I’m now pregnant with my second (my son is 4 months actual 3 corrected & I’m 5 weeks) I wasn’t given a reason for my placenta not working & I was wondering if anyone knows if it happens in following pregnancies? I’ve got a midwife appointment on the 28 but I need reassurance till then😩 TIA x
