Ectopic Pregnancy

Has anyone ever experienced an ectopic pregnancy? Lmp 11/2/16, I'm between 5 or 6 weeks pregnant. My periods are irregular. Anyways, I've been experiencing pelvic pain towards my right side of my uterus. The pain is a dull ache/throbbing at times. This morning it was pretty consistent, this evening it has toned down a little but still present. On Tuesday my blood pressure was 88/64. Today 112/52. Just wondering if this sounds like an ectopic pregnancy? Thanks for your time in advanced.
