I had sex with my boyfriend in 26 and 27 august, while my period ended in 22 august. We used condoms and I took a plan B afterwards (to be extra safe). In 5th September, I noticed dark brown spotting (kind of like this image. It’s not mine, I took it from internet). I thought it might just be a plan B effect. The spotting lasted for 4 days. There was dark brown blood, with mucus stuffs. My period was due in 15th September according to my tracking app. Now my period date is past and I’m still not having my period . So I’m scared.

Although the condom didn’t break and I took a plan B, is there any chance of me getting pregnant? I’m new in this game and every new sign scares me.
