The likelihood of getting pregnant right before your period is extremely low. For women who have a typical cycle of 28 to 30 days or longer and their cycles are regular, it is fairly safe to say that your ovulation occurred between Day 11 and Day 21. The egg is only available for 12 to 24 hours for conception.
Figure that a single dose of Adderall (any size) takes about 20 minutes to kick in (allow 30 minutes for time-released Adderall XRâs). The âhighâ peaks at about the 1:30-1:45 mark (that is, 1.5 hours since it kicked in, so about 2 hours since you took the pill).
The effects of each tablet last three to four hours. Extended-release capsule (Adderall XR): You take this form only once per day, and the effects last 10 to 12 hours. The capsule is filled with beads. Half of the beads work right away, and the other half start to work later.
