People who have been pregnant & said your legs hurt what did you mean how did it feel ? I'm on CD27 my boobs REALLY hurt, tired as hell, yesterday I woke up with a scratchy throat/voice (sound like a 12 yr old boy in puberty lmao) stuffy runny nose & then last night my thighs started hurted like I've ran a marathon, tightness in lower abdomen. Next AF due sometime in the next 9 days. Had chemical last month so who knows. Normally 28 day on the spot cycles but app says period due in 9 days. According to App is says I'm 3 weeks 6 days pregnant if I am. Would it show on test ? Whats the best test for early detection ? Please respond ! Thanks
