Growth scans

Looking for some advice, I went to the doctors at about 28 weeks due to really bad heartburn, when I was there they did my blood pressure which was 150/90. The doc also found a trace of protein in my urine, so had to go back the next day and bp was down but still high... so midwife been checking bp since and it is still high but not too high......sitting at 130-40 /80-90, no protein in urine since only one trace...also been in to hospital a couple of times due to reduced movement ( due to placenta placement I sometimes can’t feel baby)

At my 28week appointment I was measuring on the 10th percentile, had another appointment at 30weeks and was still measuring on the 10th percentile, so they sent me for a growth scan at 31 weeks, from the scan the baby was still measuring small ( just above the 10th percentile)

I have a second scan on Thursday at 33 weeks.

I have been told I will most likely end up with preeclampsia at some point

Anybody else been through this? And what happens if baby measures small at my next scan
