hi, my girlfriend has experienced nausea today morning, and fatigued whole day. Besides, she is feeling more hungry from 2-3 days. We had sex few times in last 10 days, everytime with condom. Is she pregnant? By the way, 3-4 weeks ago she had used unwanted 72 and then had regular period, and we had those aforesaid sex after that. Kindly answer me, i'm very tensed.
