Each woman experiences a varied set of symptoms, or even no symptoms at all. Also, the moment when they start to appear might be different as well. As a general rule, it is uncommon to feel pregnancy symptoms such as implantation bleeding or sickness earlier than 15 days post insemination.
On the other hand, side effects and discomfort from hormone medications to induce ovulation are likely to appear during this period (i.e. two-week wait). They can be noticed as early as on the same day of the procedure.
