I have my tubes tired approx 3 months ago, since then have had two very heavy periods which were exactly on time at 28 days. I was due on Monday and still have not had my period. I had a pregnancy test which come up negative. Getting hot flushes. Not sure if I should wait for another week or see a doctor. I don't want to be overdramatising the situation if there is no need. Not sure if this is a regular thing after having your tubes tired. Thanks for your help
