I am currently 16 weeks pregnant and would be classified as obese. I have also been horribly sick this pregnancy and have spent the past 12+ weeks lying on the couch for 8+ hours a day.

On Thursday at a doctors appointment my heartrate was elevated at 115bpm. My doctor told me to stop drinking any caffeine, which I have done.

On friday I walked to pick my kids up from school and notices my heart was racing after just 2 minutes walking. I checked it and it was 152bpm.

Ever since then my heart has been going mad. When I lay down it is between 87-95bpm but the moment I stand up it jumps to 130-150bpm. It calms as soon as I sit down. I also get a headache as soon as I stand up.

I've also been having a weird sensation in my right ear. I can hear and feel my heartbeat. It is in tune to my pulse and is almost like a throbbing/whooshing. Of course I google and up comes pulsatile tinnitus, which just seems scary.

Now I'm worried there is something wrong with my heart. My brother passed away from an untreated heart condition ten years ago.

I had to stop taking the medications I was on for my anxiety and now feel so worried and scared.

I'm trying to get an appointment with my GP but so far no luck. I'm only 30, I dont want to have a heart attack.
