Hi would request you tonplease help us am my gf has missed her periods. It's been more than a month since she had her last period. we had sex on her birthday, although we didnot used condom but we were cautious. we have checked for pregnancy with the kit that we get in medical store but it was negative. She consulted a local doctor as well & she gave her Medroxyprogesteron dose for 4-5 days but still nothing happened. plz suggest what to do as we dont want to involve parents before marr
