So I've been trying since Jan 2015 but had periods again starting Nov 2015, so had regular periods since Nov 2015, I've been using clear blue ovulation tests, been ovulating most months, 2 months since Nov I forgot to test and left it too late, anyways ovulated 3 weeks ago, I use a app to show when period is and it's been acurate, I'm 5 days late , I've been testing every day since and have all been negative, I just don't know what do, I've had slight cramps today and on day period was due, felt sick and dizzy this morning at work but don't know if that's anything. And I'm so hoping I'll be pregnant , im worried it's my body tricking me, we r trying for first baby , can someone help please
