How do you deal with the erratic cycles?

So my cycles are becoming odd at 47. I was on Birth Control from age 15 to 45 only going off a few months three times to get pregnant. I absolutely have no idea how to deal with not knowing exactly when my period will start. I've been off birth control for about a year now at first tracking my periods. They were pretty regular around every 25 to 27 days now they are beginning to get longer and longer between them, but then we'll randomly go back to a shorter time again I work full-time outside of the house and often sitting in meetings and traveling, etc.. I am extremely paranoid about having sudden heavy bleeding in public. I cannot walk around with a pad on at all times however because it feels absolutely disgusting and I don't think it's good. I'm also paranoid about having sex because I'm afraid I'll start bleeding all over the place with no notice. How are you people dealing with all this? What do you do? Do you just walk around with a pad on at all times? Do you just ignore it and hope that never happens to you?
