I'm a 20 yr old female and I've been on Yaz fo 3 months and I'm on my 4th month taking it. It's been helping me so far as far as regulating my period but I was wondering if I can speed up my period a little bit early. My boyfriend is going to be in town after haven't seen each other for 5 months and my PMS is very irritating. I'm extremely constipated and skipping period altogether will just make it worse. I have 5 active pills left and he's coming in 7 days and my period usually come by the third sugar pills. I would like my period to come in 3 days or 4 days :( not skipping it any suggestions??
