A 17-year-old female asked:

i got a blood test for my beta- hcg 4 days after unprotected sex and was negative, is 4 days to early to test?

Testing: Yes. Of course. Conception takes one to five days after sex to occur. And then a fetus is not in any way physically or chemically to the mother for ten to fourteen days after conception. This has to happen before any test could be accurate. I cannot believe any honest doctor would spend money on a test in this scenario.

Depends on where you were in your cycle, that is early. If you had sex at mid cycle, the blood test could be positive before a missed period.

Hemoglobin hematocrit and red blood cell low counts and glucose and nitrogen high what is cause

Numbers are numbers: Lab results are numbers, and numbers are just numbers. They have little meaning without looking at the whole person. Low hemoglobin, hematocrit, and red blood cell counts means blood cells are not being made fast enough, are being lost (through bleeding), are being broken up, or any combination of such problems. Glucose goes up from increased body stress, inadequate insulin, I.V. Glucose, etc....

Several suggestions: Evaluate your routine to determine how long it takes before the discomfort begins. This will help you determine when to stand and stretch, do isometric exercises, or a combination of both. Evaluate your chair and if possible, obtain one that has at least three adjustment. Seat height, armrest, and lumbar.

Blisters under: Toenails are quite common in sports participants. If you're able to drain it, apply a topical antibiotic and wrap it in a band aid, that's about the best you can do short term. You might want to check on the size of the soccer boots. If too small, they can be making things worse. Also, i hope the coach/trainer has them wearing running shoes for the pure running workouts.

She might try wearing two pair of socks on each foot and see if that helps. This was something I was taught back in high school by my coach and it worked for me. ( to prevent the blisters, not treat them.)
