I had the IUD removed June 28 and had unprotected sex the day I got it out. Then got my period for about 5 days which ended June 4th. Then on the sixth I had unprotected sex 4 times. Haven't gotten my period this month. Could I be pregnant?"

Which IUD was it, there are two types, and removal has different effects depending on type

Also, the removal can have some side effects affecting your cycle..

Could you be pregnant, of course.. you had sex. The IUD is one of the better birth control methods, in preventing, or ending pregnancy, but also, one that is easily reversed.

With that said, it can take a healthy couple, who are tracking the ovulation by medical means ( not online charts) up to a year or more for pregnancy sometimes.
Others by luck, get pregnant from first time..

So, yes you could be pregnant. So you wait another two weeks, and if no monthly cycle, you test for pregnancy using first urine of the day.

Note on the two types, depending on design, I did mean one has a hormone release, the other does not and is just copper

Yes, you could be pregnant, but it would be too early to tell since it has barely been 24 hours since June 28. Or do you mean you had it removed May 28?

You don't mention if this was a hormonal IUD, such as the Mirena, or a non-hormonal, copper coil. If it was the Mirena, it is going to take time for the hormones released by the IUD to leave your system causing a possible delay in conception. Not so with the copper coil.

It is possible that your period will be delayed for a month or two due to the removal of the IUD. It is best you wait until your period is about 2 weeks late and then test using first morning urine.
