I'm quite nervous and could use some insight. I had a 5dt on Friday, and yesterday, 2dp5dt, I started spotting. At first it was pinkish and is now (3dp5dt) dark brown. I googled implantation bleeding and it seems Ike the timing could be right, but I called the clinic where I'm being treated and they said its probably from the medicines I'm taking (estrogen, progesterone, baby aspirin, metformin). Is it at all possible that the spotting could be mplantatation even though they didn't tell me so? I'm trying to be hopeful, but it's scary to see the spotting!
