<human>: I met Jim (25 M; name changed) about 4.5 weeks ago while he was visiting his brother in my town. We ended up really hitting it off and having sex multiple times. The first few times, we were really vigilant about protection in addition to the IUD that I've had for two years. The latter few- not so much.

He ended up leaving shortly after for medical school in a different state, and we've sporadically kept in contact since. At the very least, he will be in a different state for at least the next 4 years due to his med school and my law school. 

I've been feeling really off for the last few days (tenderness, bloating, and random cravings) and attributed them to an oncoming period. However, I'm now a few days late and the strings on my Mirena are nowhere to be found; I took a home pregnancy test tonight and am absolutely terrified.

What do I do? I always thought that in a situation like this, that I could quietly get an abortion and not have it completely derail my life. In a situation like this, how much should I tell him? I've only been with him since my last period so there's no doubt about paternity. I think I might have let the cat out of the bag tonight when I was reacting to the test, though.
