So it's been a long time since I've used progesterone. I had pink spotting/brown spotting on Friday night, Saturday, and Sunday morning. I've been taking 200 mg of prometerium twice a day. I thought maybe my period was starting. I had a negative test yesterday morning and this morning. Do you think the spotting was a fluke? I always thought I started my period even when I was on the supplements. So help me out. Help me with the crazies in my head. I'm 12 DPO. Expecting my period to start tomorrow. Anyone with any of these experiences? Help me out ladies! Should I stop the progesterone and see what happens? Test again tomorrow? Wait til Thursday? Call the RE and get a blood test?
