I had some very very light pink spotting nd just a small amount could barely see it at that... Now i just have brownish white stretchy mucus (tmi) sry! Ive been quite sick in the am....and having horrible headaches! I have a drs apt this friday but the wait is killing me! Plus i have to take progestorone as soon as i find out im pregnant.... Anyone ever been through this? Thanks for your input, and no rude remarks please. Thanks and god bless!
