I was supposed to get my period 2 weeks ago, and I got bronchitis 2 weeks ago. My period is still late, and my bronchitis is still here/on its way out. Could this be why my period is late? It is usually not 2 weeks off schedule. Also on the same note, my pregnancy test was negative but I have heard a lot about false negatives, is there anyway to induce a period, or to be 100% sure it is negative. Blood tests are just expensive and I dont want my parents to find out
