Hello everyone, at 9DPO I tested positive for pregnancy, I am now one day before missed period. I took a couple test yesterday and the lines were lighter, and then I started spotting. (Very little) my husband and I did have sex earlier yesterday morning... this morning I took a couple more cvs brand test and the line was hardly there, I was sure my Hcg levels were dropping and preparing me for miscarriage. Well, I went ahead and got a first response and got a BFP... even darker than fridays test on FRER. I have been having some moderate back pain, but nothing that is severe. The first test is from Friday, the second, from this afternoon.... any opinions?
