Ok so I've been in a new relationship for 3 weeks and two weeks ago we had sex ......(and a lot of it) but we didn't use a condom and for about a week I've been feeling really sick my nipples are sore and really sensitive I can't eat cause everything h tastes different and smells weird so what I'm asking is , is there a possibility i have a bun in the oven? I've done tests and they're negative
