So af was due March 10th.. And she still isn't here all hpt have been negative.. I updated glow and added past months to the app. Now glow is saying I didn't ovulate in February and it changed my ovulation days in March.. So I'm super confused on when af is actually due.. My boobs have never been as sore as they are now, and heavy feeling.. I'm not bloated or have any cramping.. We bd last night and I went to the bathroom before and there was light brown when I wiped.. I went to the bathroom after and there was still a very little brown there.. What could this be? Could this be inplantation? It says I was supposed to ovulate March 2-8th..
