Symptom questions?

Becky • Mom of 2 💕
I justed stopped my birth control a little over 2 months ago. All this month I have been on and off nauseas (no throwing up), heart burn like crazy, and now a swollen vagina... I know awkward to bring up. It's not in pain just noticeable. I took a pregnancy test a few weeks ago but just missed my period this week. Sometimes I am irregular so idk.. Are any of this things symptoms especially so early?? Anyways thanks!!
