4 days ago I got started to get sore nipples. When I'm wearing a bra they're fine but when they're touched or if I'm just wearing loose clothing like a night top they're sensitive. At the same time I started getting a thicker, white discharge and lower abdominal cramps after I orgasm. I did a home pregnancy test yesterday and one with the doctor (who was useless) today and both were negative. She swabbed for thrush, bv, chlamydia etc but didn't suggest any other tests. I've been with my boyfriend for 9 months or so and have an implant so don't have regular periods and I've never had any of these symptoms before. Any ideas?
