Me and my husband have been trying to have kids for 1 year. Using the <a href="">glow app</a> my periods are always normal and on time. My period was supposed to come on July 14th. It is now July 27th and I have not seen my period yet! I have taken 3 pregnancy test all 3 were negative. I don't want to loose hope but it hurt to see those BFN's. I have a doctors appointment august 10th. Has anyone else gone through this problem?
