tubal

I had a tubal after my second child about 3 years ago- my hubby and I went on vacation and ever since my nipples have been EXTREMELY SENSITIVE!!! I looked and that was the highest chance of pregnancy as I was "ovulating".  Anyone know what the chances are that I could be pregnant?? Last time I had this sensitive I was pregnant- my MiL had the great advice that I just had consumed too much caffeine and needed to back off. 😒.
