My girlfriend has had regular cycles up until May, where she missed her periods for May and June, received her period for July. We engaged in genital to genital activity (shallow penetration for a brief moment) on August 22nd with a condom on, I peed multiple times beforehand, and there was withdrawal as no semen was present around the vagina during ejaculation.
She seemed to have missed her period for August and we took a pregnancy test 2 weeks after the 22nd which resulted in a negative. In the end she ended up getting her period September 4th or 5th-September 8th or 9th respectively.
However, her periods usually last for 5 days but this cycle was only 4. She said bleeding and flow was normal and not spotting, and cramps felt like a normal period. With her period ending on the 8th or 9th, on the 10th and 11th she experienced morning sickness and phases of feeling really hot which she has never felt after her period has ended. Even though it went away now, should we be worried about pregnancy? Thanks for the help. Mainly the 2 days of morning sickness worried me
