So I've been cramping a lot the past few days, I was told that's normal and nothing to worry about unless I start bleeding. My test lines are not getting darker as the days go on they appear to be getting lighter. These are CD 30, 31, 33 and 34. So I've been worried anyway, and last night I started spotting, only light and it was pink, but all of this combined I was really worried, so I rang the emergency number I was given by my gp for the delivery suite, and they told me I couldn't go there because I was to early, she told me to go to A&E. So I have done, i sat in urgent care for 2 hours before I was finally seen, i explained to the doctor all of this about the crams, the tests, ghe spotting, and that i got pregnant using clomid. The doctor took a urin sample and did a test, it came back negative, all he said to me was 'considering what you have told me and the fact that this test is negative, you have probably miscarried, but I don't know.' He told me i need my bloods taken so I have to go back to the hospital tomorrow to have my bloods done. He then rang the early pregnancy unit, I could hear the call from where i was sat because the phone was pretty loud, the woman was so rude and would hardly let the doctor talk. I then herd her say 'well we can't have here here, we only deal with women who are "actually pregnant"'. Are you F***ing kidding me!? So now I am no less worried or confused as I was before I went in. Can you guys tell me if these tests are false positives, am I just seeing things? My bleeding has stopped now, if I was miscarring would it continue to get worse? I have no clue what is going on or what to do.
