Hi. I am 28 years old. I was on the pill from the ages of 16-21. I started taking Ortho Tri-Cyclen Lo about 2 weeks ago. I have noticed a distinct change in my personality and my boyfriend notices too. I am moody, easily aggitated, depressed, no sex drive, not affectionate...... not myself at all. It's like I have PMS 24-7. When I went off BCP years ago, I noticed a huge change in my personality. I became more easy-going, my libido went up; I felt great. That is why I hesitated going back on BCP for so long. I want to stop taking the pills today. I have one more week of pills before the sugar pills. Should I do this? Will it mess up my cycle? I know it will make me get my period in a few days, but will it do any harm? My only other side effects are sore nipples and bigger boobs, which I don't mind! Thank you for any advice.
