Depending on the type of IUD (some have expiration dates), so if your IUD has expired or is not positioned properly in the uterus, it is no longer providing protection. With the pill, if taken perfectly it works 99.7%-99.9% of the time, so 1-3 women out of 1000 will still get pregnant. In the real world its effectiveness is approx. 97% because people forget or miss pills. So even though unlikely,it is theoretically possible to get pregant using an IUD and the pill.
You could get pregnant if you had unprotected sex in the five days before you had the IUD removed (if it was a hormonal IUD like Liletta, Mirena, or Skyla) or in the first seven days of taking the pill.
Yes, you can be pregnant if you had sex in the days just before the IUD was removed if it was a hormonal IUD like Liletta, Mirena, or Skyla. Consider using the morning after pill if you had sex in the last five days. If you do not want to get pregnant, start another method of pregnancy prevention as soon as possible.
Getting pregnant on the pill is unfortunately not that difficult. Miss a pill, or be on a pill that does not contain a high enough dose of hormones for your body and it's about like taking a sugar pill everyday. Except in some drug interactions, the amount of hormone is always strong enough to be used as contraception. Otherwise, sometimes the amount of hormones isn't appropriated and you experiment some side effects. In those cases, changing for a different pill would be preferable (we might say "this pill wasn't strong enough for you"... but that NEVER means that you were at risk for getting pregnant). The most common factor is when you miss a pill. IUD's work by not allowing a fertilized egg to implant in the uterine wall. The fact you got pregnant on the pill is not actually going to have an effect on how an IUD works. However I strongly suggest that you discuss all the risks of IUD's with your doctor because they have in some cases cause permanent damage to woman's uterus. If you intend to have children in the future this could be complicated.
Fertility returns to your baseline after removal of the IUD. Whether it's easy to get pregnant after removal depends on your fertility, not the IUD.
To switch from the IUD to the birth control pill, start taking the pill seven days before IUD removal if possible. Otherwise, start the pill the day of IUD removal and use a backup method of birth control for the first seven days. (The exception: if you get Paragard removed and start the pill during the first five days of your period, no backup is necessary. That doesn't work with the hormonal IUDs, though.)
The doctor can't see if you are pregnant while inserting an IUD. Your health care provider will ask questions and probably do a urine pregnancy test to make sure that you are not getting an IUD when you are already pregnant.
Pregnancy on the IUD is unusual. Bleeding with the IUD is not a special sign of pregnancy. If you think you might be pregnant, take a pregnancy test.
Not if you are on hormonal birth control (The Pill, patch, shot, IUD, ring) and used it as directed.
No
You should remove your IUD if you want to get pregnant, if you are pregnant, or if its useful life is expired and it's time to replace it.
There is no special risk from getting pregnant right after you stop using the IUD.
A positive pregnancy test is the sign of pregnancy with an IUD.
