Please help me.. I beg for your answers

Nybol • Married to my best friend, we have a 4 year son, mc in March and may 2014. Now pregnant with rainbow ( May 2015)
Good morning everyone 
​I have a very clueless question I'm still waiting for a doctor answers.
​I'm on my fertile days and my opk came back positive so my husband and I start bedding. But I notice some spotting and did a research online. And it came back saying women who spot during fertile days it's a great sign of fertility. So I was happy and this morning the bleeding got worsted and just took a pregnancy because I had a feeling. All the five test came back positive. My DH Suggest I go to the ER. Any answers will surly help.
