I had my IUD taken out in August and my body was all over the place for the first 3 weeks until I started using a natural progesterone cream. I really have no idea when I should have gotten my next period because I had bled for two weeks earlier this month. I started getting lower back aches and sore boobs so I took a test this morning!  From a due date calendar online it says baby is expect June 11 :). Praying for a sticky baby since my body was so weird before!
