I've been with my boyfriend for 2years. I've only been with him. We don't use protection. My period is 3weeks late. I took 2 test 3days after my af was due. Still hasn't came. It's been 3weeks and I'm having some signs it want to come on. But it doesn't. Frequent bathroom trips, headaches, sensitivity to everything, taste buds totally off, and lower back pain. Help please??!!!
