Hello, I am 26 and this is my first time on a bc. My doctor Prescribed it to me to help me with my pms, cramping, and acne. It seems to be working for the cramping and heavy periods. I'm not too sure if it is actually working for my pms or if i have just been dealing with things in a better way. My acne hasn't changed at all, if anything i feel that it has gotten a bit worse. I experienced horrible horrible headaches and nausea the first month. The second month was a little better, and now the third is a lot better. Ok but now the reason that i am here is that i have been experiencing bad constipation to the point where i have developed hemroids. I have always had a few problems with my bowels but never this bad! Before Yasmin i was pretty regular with no trouble. I haven't changed anything in my diet or life other than started Yasmin. So I think its being caused by the pills. I'm on my last week of my third pack. If anyone else has experienced can you please let me know. If it is the pills, I'm not going to start on a fourth pack! Oh 1 more thing, has anyone experienced sudden heart palpitations because of the pill? It used to happen more during the 1st pack and has subsided a bit but still happens at times. It really freaks me out because it will happen over and over again when it does. Any feedback is greatly appreciated, thanks!
