Stomach Pressure And Sensations In Early Pregnancy, Is This Normal?

I suffer from anxiety. Last night I woke up w/ tachecardya like heart beat and felt like I was having an anxiety attack. During this episode I felt like someone took there hands and pressed on my stomach and ran their hands down my stomach toward my crotch while pressing down.
I have experienced this before, pregnant last time, during an anxiety attack.
Today, I have been having a fullness feeling and have begun to feel like something isnt sitting right on my stomach (queesy feeling). I wouldnt really say its a motion sick feeling or a fish flop feeling, its just a feeling like something isnt sitting right on my stomach and is causing it to get upset.
I have been constipated to a degree but having bowel movements daily, just takes longer.
Any one else experienced similar while pregnant? Or, had similar sensations when experiencing anxiety during pregnancy? Im wondering if this might be normal or, another miscarriage about to happen.
I am only 6 weeks pregnant. I have had 5 miscarriages previously all at around this time frame. I havent been cramping or spotting or any thing so Im not sure if the pressure is normal, especially from anxiety, or if it means the pregnancy isnt viable. I dont go until the 16th for an ultrasound. Thanks!

Can I take my blood pressure meds and supplements before my Cholesterol test?

I have heard that one should not eat anything 8 to 12 hours prior to giving blood to check your Cholesterol levels and receiving an accurate reading. But does that include medications? Every morning I take my Blood Pressure medication along with a Vitamin D Pill, a multivitamin, and a Fish Oil Capsule. Should I NOT take any of these drugs until after my blood test, or is it ok for me to take them prior?

Gauge pressure + force on a large aquarium?

The aquarium is14m deep, 10m wide, and 12m long. It will be completely filled with salt water at 15ºC (density = 1062.8 kg/m3). It will stay dark, except for ultraviolet light (to highlight some species of fish.

I’ve got to figure out the guage pressure at the bottom of the tank, and again at 7m from the bottom.

Also have to find the total force on the front glass of the aquarium.

Any work shown will be greatly appreciated. Thanks in advance!
I’ve searched the web for answers on how to solve this, and have found nothing. Need someone that knows what’s going on please.

Water pump pressure for shower?

Hi, I need to create a portable shower and was going to go the DIY route, i wanted to use water pumps normally used in ponds, aquariums etc etc as the means of creating water pressure for the shower, the shower need not be really strong in pressure but it should be strong enough such that a person can take a bath using it.

height of the shower would for sure be less then 6 feet,

question , water pumps are rated at gallons per minute or some equivalent rating, how strong a pump or how much GPM should i be looking at ?
wait I think I have to emphasize that this is a portable shower, so the source of water is a tub of water so the pressure has to be generated by the pump.
