Hey ladies. so gonna try to make this as short as possible. but please anyone please share your experience if you can relate. oky so my AF is always on time. ...I am now 8 days late. ...all my PMS symptoms are no where to be found. example: right before AF I usually get very watery cm, and my boobs get really sore. ......well this month I haven't had none of that. the last almost 3 weeks now I have been having random cramping. and like a pinching twinging sensation on my lower left side. ...a couple nights these last 3 weeks I have felt nauseous but didn't actually get sick. and there was one time only that I got really dizzy I felt like. ...I tested at 2 days late and 6 says late and both were on frer with fmu and both bfn.....I am just wmadeirng if it is possible that I am still have a chance of getting a bfp or if I'm out? ...I have heard a lot of of stories of women who don't get bfp or vgfl until like 2 3 weeks late...I am wandering what your opinions are and if I still have a chance this month....the picture is from the app I use to track AF. and ovulation. the flowers are the days I am fertile the egg is the day of ovulation and the hearts are the days we bd.
