Question about Post Ectopic Pregnancy

For all you women who have had an ectopic pregnancy and had surgery that removed a tube.. did it take awhile for your cycles to be regular again?

I had my surgery on Feb 12th, 2016. Had my first post surgery period on Mar 13, 2016. Today is April 11, 2016 and I still have not had my next period. Prior to the surgery I was like clockwork with a cycle of 26 days.. making me about 5 days late today.

How long would you recommend I wait before consulting a dr? Is it normal to be 5 days late after a ectopic pregnancy? Took a pregnancy test last night and it appeared to be negative.

Any help, tips, guidance, etc. is appreciate! Thanks :)
