Had my tubes tied 15 months ago, started spotting a 2 weeks after period, now has turned moderate with some clots. Shoulder pain, now pain in upper middle of my back, and when I take a breath. Talked with doctor before the back pain and they said to take pregnancy test, came back negative. no other symptoms, been with same partner for 4 years. I do annual pap, dude in October. Should I be seen before?
