For the past 6 days I have had cramps and bad nausea really bad and gaged a few time which isn't normal I have a good control on that. I haven't had a period since May 13-17. I got my iud out on June 29. I took a pregnancy test this after noon and maybe there is a very very very faint line. I also am craving salty food and gag at the food I (used to) love. Also my veins are really visible for the past 5 days. What's happening?!?
