Hi all! My bf and I had sex about two weeks ago, no protection but I do have an iud put in and he did not cum inside or at all that night.  A few days ago my nipples (not my whole breast) have been very sensitive and as the days past they become more sensitive. Today, I can't even touch them. I have had very mild nausea. Could it be pregnancy? No AF yet, no signs of etopic pregnancy with the iud but I'm still curious. Any ideas?
