TMI PIC help!!

Jennifer
Ok this coming Monday would make me 10 weeks late for my period. I've taken several pregnancy tests and a blood test about a month ago all negative. I've been lightheaded lately and I've gained 3 lbs but not eating a lot. Boobs have been sore. This morning I woke up to this and idk if it's my period or what. I've never seen anything like this. Can anyone help?
