User avatar Hello,
In what way is your menstrual cycle irregular? Thyroid disease is known to be associated with many irregularities in menstruation. Your case would depend on how controlled or 'uncontrolled' your thyroid condition is. If you are taking too much medication for example you may experience infrequent periods. If you are taking too little then you may experience excess or heavy cycles. Again, BCP use is designed to disrupt normal menstruation. If used irregularly you will experience irregular periods.

If you are referring to one incident after sexual intercourse then this is known as post-coital bleeding. This could be related an infection (amoxicillin may have something to do with that), cervical dysplasia, uterine polyps, fibroids or adenomysis. Post coital bleeding warrants urgent medical consultation.

Best regards,
