Stress can: While the Amoxicillin can interfere with the effectiveness of the hormones in your birth control (that is why you always use a backup method of contraception if on antibiotics and the pill), it should not delay the onset of your menses. However, the stress you talk about certainly could have an effect enough to delay your cycle.
