I’m 17 and a few days ago I had sex but the condom came off inside me (awkward) but I took Levonelle to be on the safe side and the lady told me that it’s not 100% effective. I have a brain mri on the 4th of July and I know that mri’s are dangerous for baby’s especially in the first trimester however I’m not due on until after the mri so do I take a pregnancy test before it just to be sure? Also how likely am I to be pregnant?
An mri will not be harmful to a pregnancy at all - the only time they would even ask is if you are having an injection of contrast (dye). You can phone the hospital beforehand if you're not sure if this is involved - you should be able to have your scan without it anyway (this is also the case for people with low kidney function)
Yes it is possible that it’s not effective if you’ve already ovulated but I guess you don’t know your ovulation day. Don’t panic and if your period is due in less than two weeks take a test when your due on. That will be before the mri and you’ll know for sure.
I wouldn't worry too much. You only have a 25% chance of getting pregnant each month anyway even if you are trying. You have also reduced any chance by taking the morning after pill. Yes, it is possible for you to be pregnant but highly unlikely. I would take a test if your period doesn't arrive and forget worrying about the MRI.
