My girlfriend was worrying about her late period, she said November 1 2017 is her last period so basically December 1 2017 is the next but she didnt get his period at all and it last 2weeks late before we meet then December 15, 2017 we had sex but by using condom but then we try to unwear the condom and try to get inside her but in just a seconds, we never penetrate at all and mine was so very dry no wet at all now January 1 2018 two weeks after weve met she never had her period at all so we were wondering if shes pregnant but I asked her if she get signs of being pregnant she said nothing, I ask her like nausea/food craving, breast tenderness and back pain she said she feel normal at all nothing of like sign she feel at all. What was your opinion about that coz were both wondering please help me thank for the answer if ever.
