Hi, I’m really confused on this, maybe I’m just looking for things that aren’t there. Let me just clarify this (I’m not trying to conceive) but I’ve had occasionally unprotected sex with my boyfriend, but always using the withdrawal method. We never had any accidents that may worry us, but I still get a lot of anxiety cause I’m very irregular. However, followed by this app I was supposed to start my period today… and I did (or that’s what it looks like) as soon as I woke up. And followed by my “<a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">Period Calendar</a>” app I was 3 days late. My concerns are that it’s a little lighter than usual (although it’s the first day) I’m just scared it may be implantation day, even tho I’m in the right time to be starting my period. Can someone help me confirm if this looks like period or implantation?
