I've had an IUD for 7 months, taken 2 negative pregnancy tests. However, I'm experiencing nausea, swollen breasts, a hard lower abdomen, and spotting. Could this be a sign that I am pregnant?

It is unlikely that you are pregnant if you have been using a contraceptive intrauterine device (IUD) for 7 months and have had regular periods. However, if you are experiencing symptoms like nausea, swollen breasts, and spotting, it is always a good idea to consult with a healthcare provider to rule out any other potential causes.
