It is possible u could hav been pregnant and miscarried
Well, women do get pregnant after tubal although it's not common and when they do, it's often a tubal pregnancy. What type of tubal did you have? If it was done with clips, they can come undone. Tube are then open for pregnancy. If they severed the tubes, that is trickier but what happens (rarely) is that scar tissue forms in such a way that it kind of creates a new tube. But pregnancy after tubal IS dangerous because it is so often a tubal pregnancy which is not viable and can kill the mama. There is nothing to be embarrassed of, I'm not sure I understand that. Getting pregnant after a tubal shouldn't be embarrassing as that isn't your fault. And since it has a possibility of happening, it's better to know, right? You need to know in case it happens again and has a worse outcome if you were indeed pregnant. But, you likely weren't pregnant since you had a negative test (often right after miscarriage, you'll still get a positive). But it could have always been a pregnancy in jeopardy and HCG could have been low and thus, not triggering the test. A blood test would determine if there was any HCG in your system. You normally have to be about 6 weeks or further along to have nausea. So, I'd not worry so much about symptoms you had. And you don't need to go to the hospital but do need to see a doctor in my opinion. A regular doctor's appointment with your ob/gyn to discuss this matter for planning in the future. good luck
