I’ve been on birth control for 4 years I stopped taking it on Jan 19th. I got my period January 21st than on feb 1st I had unprotected sex and took plan b one hour later. I was suppose to get my period Feb 18th now 11 days later still no period and I’ve taken a few pregnancy test and each one has said negative.

Should this be a concern that I have something wrong or does it have maybe something to do with stopping birth control??

Any idea welcome. I don’t have health insurance right now due to losing my job so I’m having a hard time affording to go to the Dr.
