So I went to the doctor because I had a weird period that was really light, and had a feeling I was pregnant as well has having a lot of symptoms. I said to her I was getting faint positive on strips test but negative on FRER, she said it’s highly likely that I had a chemical pregnancy, but she didn’t do no test (blood test) to confirm. However I didn’t get a faint like until AFTER I had bled? All she told me to do was to wait a week get a decent test and test again, if it’s a negative then I’ve lost the baby? Have anyone else experienced similar, what was your experience when you had a CP x
