I have irregular period cycle. Average of 32 days. I had protected intercourse 23 days after(23rd may) the first day of period(30 april). In this duration there were multiple instances of alcohol consumption and stress as well. My period was supposed to start from 29th may although it has not occurred yet. I even took prega news pregnancy test a day before(10th june) with first urine in morning that came out to be negative. There is no nausea,morning sickness, excessive urination or vomiting. No vaginal discharge or stomach ache as well. Today i noticed erect breasts nipples. Are there any chances of pregnancy. How can I be sure. How can periods be induced fast ?
