How do you differentiate an extremely late period and a chemical pregnancy because my period is never 3 weeks late but the painful period is normal. Trying to just get an explanation l. My heart broke when I started 3 weeks late because the same day I started is the day I was confident I was pregnant and went and got a blood test. I'm just really confused TTC is taking the biggest emotional effect on me it makes me not want to try anymore. Ladies I'm sure you know what I'm talking about when you know how your body is and you know your not crazy. That's how I feel except my body wants to do whatever now and throw me off guard then make me feel and look crazy. Too bad god didn't cast down my own personal instruction manual handbook😩😰
