Got an IUD about a year ago a few months after my baby was born. it stopped my periods for quite awhile then they started coming back once a month like normal then they stopped again a couple months ago. I notice my belly looks a little bigger, I brought it up to my husband and he agreed and got all excited. he thinks I may be pregnant so he decided to rush to the store to get a pregnancy test now. I kind of think I may be pregnant but not getting my hopes up. My husband on the other hand is crazy excited and wants us to have another baby so bad. I wanted to wait a bit longer. but we will see when he gets home. ahh feeling so many emotions right now! sorry for the long post lol
