Oh okay I figured that @sparklymama

yep I was scared too because how bad it threw off my cycle I was testing like crazy but I wasn't pregnant went to the doc and they told me about the large dose of hormones and how it affects the cycle making it irregular for awhile

dang yeah I had two periods last month now I'm late this month but I took a test it was negative @sparklymama

plan b is a major dose of hormones so it throws your cycle off it took 2 months for my period to regulate back

It makes you irregular at first

It worked when I had to take it
