Vaginal ring  
Used for 3 - 6 mo

  •  4 days ago

NuvaRing  

The first few months weren’t awful, had regular side effects like nausea, anxiety & tiredness. The main function of the ring for me was to skip my periods & for the first 3 months it worked great. On my 4th ring a few days later I started to feel incredibly nauseous (I didn’t vomit) & the day after I started bleeding, I spotted every day for over a month & still spot every other day, I also had had a large sack of my uterus wall come out which is apparently a side effect when your hormones are unstable. My hips, pelvis, back and legs were aching to the point I struggled to walk. I removed the ring & had instant relief. The nuvaring has made it so I physically can’t have sex as it feels like my vagina is on fire as soon as anything’s inserted, when I took the ring out for a few days this went away & came back the second I reinserted it (it’s also irritated my partners penis). I don’t know if I’m just very sensitive down there or my body doesn’t agree with having a foreign body inside but this just simply hasn’t worked for me. It’s also difficult to get in the right position. My boobs have gotten bigger tho atleast but so has my tummy from the awful bloating!! Swapping to the patch today & hoping it works.

NuvaRing  

I have had the Nuva-ring for years. It's brilliant, no side effects, it gives the hormone dose at the point in my body I need it so I know less hormone is swirling around my body and going through my liver. Surely that's a good thing. I don't think GPs prescribe it here in the UK nearly enough as possibly more expensive than the pill? I was living in Europe after the birth of my second child, initially I was put on the mini-pill and immediately fell into a very low mood which I hadn't felt the weeks after the birth so knew it was the mini-pill that had effected me. I was taken off it straight away and it was suggested I avoid progesterone-only contraceptive as I am probably progesterone-intolerant (beware anyone on the Merina-coil - so many don't realise progesterone can give you depression). I was then given the Nuvaring which I have been on ever since. Oestrogen and me are happy bed fellows. I am also now on HRT which I can take with the ring. When my oestrogen levels dipped as I hit 50 yo the oestorgen in HRT once again lifted my mood. It's all trial and error but only we know what works and what doesn't.

NuvaRing  

NuvaRing greatly affected my mood, at one point I thought I had depression and got prescribed antidepressants by incompetent doctors. The second I stopped using NuvaRing (based on INTERNET RECOMMENDATIONS), all my mental problems went away

SyreniRing  

Things started out really well. No side effects and I didn't take ring breaks so no periods. My skin got less greasy so I got fewer spots, and I had 3 months blissfully free of painful period diarrhoea. Sadly after 3 months I started to get breakthrough bleeding every day and minor versions of my old period symptoms like back pain, cramps, and digestive upsets started to flare up. I tried removing my ring but that just made it worse and within 4 hours I was having a bad time on the loo and put a new ring in just to make it stop. The new ring helped, but now I feel kind of trapped having a constant mini period all the time with no alternative since the only pill that worked for me in the past has been discontinued, and progesterone only contraceptives have never agreed with me, so nothing else seems as convenient as the ring. All in all, bit of a mixed bag.

SyreniRing  

Switched to the vaginal ring after using the pill. When first trying it I could feel some pressure in my lower abdomen but this feeling passed after 1 day and havent had it again since using it. The first 2 periods I had were shorter but heavier than usual but after each period (basically the break week) each period got lighter and my 3rd period was lighter than my usual. Apart from that no other side effects - the above ones I experienced I would say linked to my body adjusting to a new contraception (similar to the pill where they tell you the first 3 months you may experience some side effects). I dont feel as moody as when I was on the pill and the great thing is I dont need to remember to take something everyday so the peace of mind is an additional benefit.

SyreniRing  

My mood spiralled quite rapidly - by week three I was in what I would describe as a state of depression and had to remove it a few days early. I felt as though there was a grey cloud over my head constantly and I was randomly crying several times a day. It was actually interesting tracking my mood because it was a stark difference to how I was feeling prior to using the ring. It's a shame it didn't work out for me as it was quite convenient method of protection but I couldn't endure the feelings for more than one cycle.
