The Mirena (levonorgestrel) is more like the depo-provera shot. Mirena (levonorgestrel) is a Progesterone only contraceptive that is placed by a physician inside the uterus.
IUD. Mirena (levonorgestrel) is a hormone coated intra-uterine device; NuvaRing is a hormone impregnated flexible ring that you insert into the upper part of your vagina, and change once a month. Mirena (levonorgestrel), once placed, provides contraception for 5 years, the NuvaRing for a month at a time.

1-2 months. Mirena (levonorgestrel) inhibits the growth inside the uterus and it takes a little time to grow back. With the NuvaRing you will probable have a cycle by the time you remove the second one. That assumes you use it cyclic, 3 weeks in 1 week out. If you immed. Started using continuous, 4 weeks in and immed. Switch with a new one, you may not have a cycle.

I used Mirena (levonorgestrel) from 11/18- 5/5 a week before the removal I was put on Nuvaring I used it for a week & now I want a baby how long until we conceive?

Right away. Using the Nuva Ring does not prolong your chances of becoming pregnant. It might take a cycle or two, but you should be able to conceive (chances with any cycle are around 20-25%) next cycle. The only birth control that prolongs infertility is the Depot Provera (medroxyprogesterone) shot. All the others don't prolong infertility.
