hi I'm 12 days late for my period I was expecting it on may 11th and its now may 23rd! I took 3 tests already and all came out negative. I'm so confused on what to do. I made a doctors appt for next week I figured ill wait it out a little bit more. But I just started these diet pills called phentermine. If I am pregnant will the pills effect my baby in any way? And can the phentermine make my hcg level not show up on the pregnancy test? I'm having randoms cramps here and there but they don't last for more then a couple of seconds. And my breasts are hurting me a little. I get frequent headaches! And I'm so tired(but I think that because I'm running after my 1 year old daughter from 7 in the morning). I don't have nausia really. I've been a little nausios with certain things but not vomiting or anything major! Thanks for the help in advance!

I do not know if you are pregnant, But weather or not the diet pills can really hurt you in plenty of ways including messing with your cycle. I do not know about the diet pills you are taking but some have been shown to cause heart problems restlessless, depression and tirednessdue to the fact that you do not eat properly on diet pills. If you want to lose weight do it the healthy way. You may or may not be pregnant, your doctor can do a blood test to be sure, until then I would not take the diet pills and tell the doctor that you have been taking them so he or she can adjust your medical care correctly. Hope everything turns out the way you want also if you quite taking the diet pills you may even start to feel better and start your period. Stress can also change your cycle so relax and see a doctor. Good luck.

The diet pills could definitely be the reason your periods are late
