I used to take Lady Pills, I switched to Althea and had just finished taking my first Athea Pills, I started taking them after my last day of menstruation, on the third day my husband and I had sex, we did not use condom as advised in the prescription. its now the 2nd day after I finished all the pills, I don't have bleeding yet, however, It feels like my breasts are heavy and painful, and so as my lower abdomen, does it mean That my period is coming? May I ask why do you have to advise the use of condom when the pills are not started on the day of the menstruation? thanks a lot!
