For example by the mini-pill or something? I'm a bit ignorant about these things.
I've booked a weekend in Dublin for me and DH for our wedding anniversary in Feb - our first proper weekend away since our twins were born 5 years ago, and I've just realised my period is due on the day we go, and I get very heavy horrible periods.
The weekend was supposed to be a bit of a sexfest to make up for the drought we've had recently so I'm a bit disappointed
