I don t acctualy know how this works ...but I ll try.So, I ve been experimenting with my gf last saturday and we were both naked ...grinding . So one time my penis went in (about 2 cms) and I don t know if I had any precum on it.I didn t cum in her or on her though. Now her period is late ( last time it was late for 2 moths , some hormonal disbalances IDK) and she s telling me she s got symptoms like back pain,leg pain,and headache ,bigger appetite , she was sick while taking a bus , and also she said her breasts hurt . Is it too early for that sympoms . Is she just scared ( I know I am) ?
