hey everyone! I'm 18w and 5d today. Tomorrow is my anatomy scan

.
On Wednesday night I ended up making a trip to the ER because I was having some abdominal pain and my doc said just be safe. Everything turned out fine but they checked my blood pressure twice and it was very high like 153/85. Normally it's like 130/70 or 120/60. I'm not really knowledgable about BP so I was happy I was cleared for the pain and sent on my way...
Then my doc called me on Friday and said to come in early to see a midwife before my anatomy scan they are gonna check my BP to monitor it and I may start medication... I checked it today myself at stop and shop and it's still high 145/90.
I'm nervous. On November 12 my last appt it was completely normal - I'm baffled by how it could rise out of nowhere...
Is anyone else dealing with this? What have you been doing.. I just wanna ease my fears unfortunately I've been googling

Thanks everyone
Re: High BP
There are things you can do in general to help high bp like eating right, exercise, getting enough sleep and staying hydrated but those are long term things, it won't make it go down overnight. Lying on your left side will usually decrease your bp if it is pregnancy induced but at this early you might need medication anyway. I was already warned that it might come to that if my numbers are high again. I am to go in at anything 140/90 or above.
And just FYI: when taking your own bp at home or at a store you need to sit quietly and completely still for at least 5 minutes before taking the reading. Walking, talking, even things like checking email or texting can make your numbers go up and that wouldn't be reliable reading.
Try not to worry! Many women deal with the issue and although it's crummy everything is fine. My daughter was born at 38 weeks and is a happy and healthy 10 yr old.
Good luck!
I am trying to take walks and eat better. I also stopped working (obviously that's not an option for everyone) and my Mom helps out with my daughter when I'm stressed out. I have a BP monitor and it really helps to check frequently. That way if it's high I know is time to take it easy.
I had pregnancy hypertension (high BP) with my first 2 pregnancies. I went on meds (Labetelol) at 11w with #1 and 8w with #2.
I did many 24 hour urine collections to watch for Pre-E (but it never became Pre-E - so that was good).
I saw the MFM clinic for growth ultrasounds every 4w after the anatomy scan to monitor baby's growth. I also had 2x weekly Bio physical profile ultrasounds from week 32+ to check baby's health in the womb.
I was induced at 39w as part of the high BP protocol. Safer out than in at that point b/c high BP can cause the placenta to crap out earlier than normal.
My kids were both healthy, I was fine, and went off BP meds by 6w post partum.
Monitoring is important to make sure your BP meds are working well, and to make sure the baby is doing well in there.
Good luck!
