I am a little over 6 weeks. I started taking (ORAL) progesterone 5 days ago. I have been spotting for a week and half now. Mainly brown. I had one episode of red yesterday and then again tonight. It just quickly goes back to brown. I'm cramping, but that is nothing new. I have been cramping for almost 3 weeks (ever since I found out I was pregnant). I hear that spotting is common when taking progesterone. Its just your body trying to adapt to it. Anyone have experience with this? I have a repeat ultrasound tomorrow but just trying to get some answers from other experiences. Thanks
