Paternity: It is man b. But, that is not 100% guaranteed. Fresh sperm are thought not to survive six days. The limit is thought to be five days. But, your conception date is at best an estimate. And, if two men's sperm were ready to meet the ovulated egg it could be either sperm that caused the pregnancy. Thus, in reality, you will need paternity testing. That is going to be the only valid way to know.

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.)
