I have had protected sex on the 16th of January and I had protected sex on the 27th which was my ovulation day and partner came in oral form not in the condom I took a test yesterday morning which was the day after my expected period it came up negative It’s been 2 weeks a few days since sex I also took a test 2 days before my expected period and it was negative also. My breasts and nipples are really sore and I’m having slight cramping, sometimes brown discharge and I’m really bloated. Could I possibly be pregnant someone help me!!
