Megan

Okay hello all my period is 5 days late now and I took a urine test but it was clear blue digital and it was negative but my sister said to take apart and check it and there was two lines on it but I took a pink dye and it was negative. Idk what to think now and I’m upset bc me and my bf are trying for a baby. And I’ve been emotional all day and my boobs are sore too and cm has changed . Has anyone else had issues and should I do blood work?
