Does copper coil (IUD) cause high blood pressure?

So far period have been very heavy and more painful than usual, but I’m hoping that this will begin to settle in the next few months. No breath through bleeding and causes no interruptions which is great.

I do like being on the copper coil as I have 10 years of contraception I am in a long-term relationship so do not need to worry about STI's. the first year I was on the coil I would have such bad periods 7 days long, I would have painful lower back pain, cramping, feeling weak. I would lose a lot of blood about 30 ml a day or more. It was very uncomfortable and painful however after about 15 months it subsided and now I only get 1 or 2 days of pain and then the rest of my period is bearable however still 7 days. I used hot water bottle, Solphadeine (for pain) and Tranexamic acid (for heavy period). I do like this one though as there are no hormones so I do not get bad skin, gain/lose weight, have mood swings or lose sex drive.

It took me a long time to decide to switch from the combined pill to the copper coil. For context I’d be on the pill for 15 years and nearing 30, I finally decided to get the copper coil inserted as a hormone free contraceptive and to try and get to know my cycle. I’m around 6 weeks in from coming off the pill, having had the coil put in a week before this. Overall the insertion was a very painful experience, albeit it only about 10 seconds each time (once to check/measure everything and once to insert). No one can prepare you for that (for info I’m 29 and no kids) BUT I’m now extremely happy with my decision. I had bad cramps that evening, and every so often for a week after but was able to exercise after a day. I was spotting for a little while until a 2 day ‘period’ or withdrawal from coming off the pill. I then had what I would consider my first period 28 days later. I had a bit of nausea, which was new, but it wasn’t particularly heavy. Main changes I’ve noticed having come off the pill and onto using the copper coil, is that my anxiety has gone way down, I feel less dumpy and bloated, I’m more in touch with my feelings and not as ‘numb’. I was on the pill for half my life and didn’t have a clue what to expect, but I feel more human which is nice! The coil has given me security as a contraceptive without the hormones, which is the dream really. The main thing I’ve learnt is that everyone is different and you genuinely don’t know unless you try. I’ve had a positive experience and appreciate that others haven’t but Google sucks - do what feels best for you.
