I had a tubal ligation just over a year and a half ago...I have had a normal period every month since then.  This month I am 4 days late and freaking out! I have taken 2 pregnancy tests 1, 1 day after missed period (negative and the 2nd one 3 days after (inconclusive-no result). Looking for advice. Any one else have similar experance. Don't know what I should do or expect.  Feeling overwhealmed. Hoping that someone can offer some inseight!  Thank you in advance for your time and responses.
