My periods are regular. In April 15 th I got my last periods. In may 12th morning I felt abdominal pain and I notice in toile some bleeding of clots. I thought My periods is start but after that day bleeding is totally stopped. But the second day when I am went toilet then I am fingering in my vagina and I noticed very little blood in my finger. After that on 14 th may I have done a urine test with a pregnancy kit but the result was negative. On 15 th may after discuusing with my doct I have done serum/blood BETA HCG TEST and the result was also negative. My question is that what can I do now? Can I wait for a next month periods or should I discuus for second opinion of another doctor? I am also suffering a mild low back pain and white discharge .
