Pregnant or birth control side effects?

Shakira

Okay, so my boyfriend and I decided we wanted to try to conceive in January. I stopped taking my birthday control towards the end of December (probably around the Christmas). So it’s been about 2 months since I’ve stopped my birth control, and my last period ended a week and 4 days ago. However, the day after my period I Started getting light cramps on my lower left side where my usual menstrual cramps would be and since last Wednesday or Thursday my nipples have been super itchy. I’m not sure if those are pregnancy symptoms or if my body is still adjusting to me not being on birth control? I took a test yesterday and it was negative. I do have a dr appt tomorrow but I just wanted to know others opinion. I also have my nipples pierced but they have been pierced for a year now so I don’t think that’s why my nipples are itchy.
