I have ADHD and really struggle to remember to take the pill every day. Or I just put it off and don't take it. I am the same with anti anxiety/ antidepressant meds, antibiotics - anything like that. It's weird and damaging I know - but it doesn't work for me. Also gained weight and was really moody.
I had the implant and bled constantly for four months, until I finally persuaded them to take it out. Wasn't even sexually active at this point, but still had to spend weeks persuading my surgery to do it. They kept trying to put me on the pill aswell to try and counteract the bleeding 
Have heard some good, and some horrific things about the coil. Truth be told, I'm terrified about the procedure (I have terrible anxiety, and just thinking about it makes my heart race). Also scared that if I did manage to get it put in, I would have the same side effects as the implant, and would have to go through taking it out a couple of months later. If this is anybody else's method of choice, how was the procedure? Am I right in thinking there's a coil which doesn't contain the normal hormones? This is a big plus for me - I worry about weight gain; after years of being overweight, I've finally succeeded in getting down to (just) a healthy weight. Also, does this mean the constant bleeding is less likely?
Or the depot. I keep thinking about this. But I work in a GP surgery with over 20000 patients and less than 15 are on the depot. Seems a bit strange?
Just want everyone's thoughts really. I'm dating someone (have made clear I won't go any further without STI checks, and I'm not a big fan of condoms
) and am thinking about taking it further, but need to sort this first.
