If I had sex on june 10th and 11th, and my period came down on june 23rd, could I be pregnant?

Sometimes I feel faint, dizzy, a funny taste in my mouth, frequent urination only seem to be when I am by my boyfriend which is weird, and now I have a runny nose and a headache. My period is only about 3 days and is a medium flow but this time it was 4 days and heavier but within those days it kind of went up but then came back down and got light and lingered for the fourth day. Can anyone help

Whole house fans, sizing and placement?

I think the whole house fan could be a good idea but there could be some problems because of it. The air that is exhausted by the fan has to be replaced by another air source which would be outside air. You live in an area that has very hot weather and if the fan is used during the day, your house will get hotter. A better approach would be to ventilate the attic only. I am sure that the attic or roof space could easily reach 140 during the day. This temperature would not only cause heat be transferred through the ceiling into the living space but will also allow radiant heat to go into the rooms. Ventilating the attic space will not only lower your A/C costs, but will extend the life of your roof.

Which non return valve type is best suited for high viscosity liquids?

In a reciprocating pump design I am trying to place 2 non return valves. Normally these would be a simple ball on a seat which lifts to allow the liquid to pass in one direction when the direction is reversed the ball falls and blocks reverse flow. Now the question is when using very viscous materials (like a syrup) which type of basic non return valve is best. to employ. The challenge is to have a design of valve which closes very quickly to prevent back flow. Yes it is appreciated that the reverse closing action can be speeded up using a spring. The stronger the spring the quicker it closes but on the intake port to my pump the fluid is under atmospheric pressure (open reservoir) and if a spring of too great strength is used then it is impeded to open if a spring of too great a force is used and the pump may Cavity. Any suggestions please?. For reference the inlet is at least 25mm diameter and I wish to draw into the pump on the UP stoke at least 200cc in 2 seconds

Were the joints/blunts laced with another drug?

No probably not. Chances are the atmosphere and the weed affected you. You also don't know what kind of weed it was. Everyone thinks they have a higher tolerance than others, let me just say as a person that has a ridiculous tolerance for everything myself and smoke many different types of weed, there are some strands that will knock your socks off. Plus weed and affect you differently in a concert than when your just sitting around at home. Sounds like you may have deprived your lungs of oxygen, you were dehydrated, or you had a mild panic attack which happens on weed. I've laced weed with every drug imaginable and unless the same thing happened to the people you smoked those blunts and joints with I don't think it was laced.
