HELP PLEASE!!!!

Holli
So yesterday me and my SO were having sex not but like 5 minutes in we decide to switch positions when he took it out he had white creamy stuff on him from me and it didn't stretch between my fingers like ovulation mucus it broke as soon as I pulled my fingers apart, my period is due in 2 days but I've also been peeing more then usual, my breasts are super huge and very very sore, my nipples are very sensitive and the slightest touch hurts so bad I also have noticed little pimples popping up on them more then usual, and I've had miragrianes they pass two days including today on top of heat flushing throughout my body from head to toe at random times, but I've tested today and got a negative could I still possibly be pregnant??
