This past week I ve been getting moments where I feel nauseous for about 30 seconds then it goes away, I also am having trouble falling asleep at night even when I feel exhausted, I m having lower back pains, bloated stomach, changes in appetite, fatigue and increased discharge. I m very scared that I might be pregnant, I had unprotected sex about 3 weeks ago but I bled lightly 2 days after for about 3 days. So I assumed that was my period. Another thing to keep in mind is I just stopped taking my birth control pill about 2 months ago. Please get back to me on what I should do.
