When Mandi is in a serious relationship, she takes the pill. When she's not in a serious relationship, she still takes the pill. No break from her birth control routine just because there's a break up. But when she's not in a committed relationship, Mandi also uses condoms for STI protection. Always.
Mandi carries the pills around her in her bag and when the plastic case rattles, she's reminded to take her daily dose. (That works for her, but if you need more than a little shake, rattle, and roll to remember your pill, we can help with that.)
If it's casual, it's the pill AND condoms.
