20 days late took a laxative and got my period ???

Anjelica

hello my period has been coming late for about 4 years now and for about 3 months it's been coming for 20 days late each time so don't really know what's going on with that went to the gynecologist and they always tell me I'm fine I'm obviously not fine if my period is coming late I'm just wondering is this normal for me to take a latex and I end up getting my period after that. has this happened to anyone else if so please explain
