Hi everyone! I have an interesting situation. Tubal in 2014.

I gave birth to our youngest daughter on Nov 3, 2014 via c-section and tubal done then too. Then 6 weeks after the delivery/tubal, I had a mirena inserted for regulating my period. Now fast forward to Dec 17, I had the mirena removed. I was having some pain during sex. Now, the good news is, I don't have the pain anymore but this month... I feel like I'm pregnant. I took a pregnancy test yesterday (9/10 dpo). It was negative. I'd be happy either way, pregnant or not. I'm 38 and I had 2 healthy pregnancies and 1 stillbirth. So, I'm really wondering if there is a procedure the doctor can do to see if my tubal is working and an egg can not get fertilized. Should I just get a hysterectomy? Anyone have any thoughts? My husband thinks I'm not, that there's no way I could be pregnant but he caved yesterday and bought the pregnancy test. We're concerned about the fact that I could have an ectopic pregnancy.
