Hello! I had written before about having had sex on 1st may, followed by a light period on 25th may and then continued cramping and soreness in breasts. 1 out of 5 tests came out positive with a very faint line. Today early morning i took 3 more tests. All negative. And i got my blood beta hcg test done that showed a level of 0.27. For reference, I have pcod and my routine has been bad visa vis food etc. So i still have some cramps but reduced soreness. Do I need further tests? Or is the blood test valid?
