I got my IUD out this past April and had a period for about 5-6 days. I only spotted for 2.5 days the first week of this month which was a week before I should've gotten it. For the last week my breasts have been VERY tender. My stomach started being tender yesterday and I lactated a little as well which never happens. And on Saturday, I started getting nauseous for the first time in a car. My lower back has been hurting for 2 weeks and I've been getting headaches for just as long. I have also been craving salty things and potatoes. I have also been way more tired than usual and actually fell asleep unexpectedly on my couch numerous times the past two weeks. I have been having unprotected sex with my husband because we are trying to get pregnant. But, I've taken a pregnancy test this week and one last week but both were negative. Doesn't it sound like I'm pregnant??? I am so confused!
