Possibility I might be pregnant....

Miranda • Had 1 ectopic pregnancy 2020. Praying for baby #1 💗
So for the past week I've been getting sick. None of my food will stay down and everything stinks and I've been super emotional the past few days. I took a test Friday night and it came out negative. And it's like ever since my husbands brothers gf (tinue) found out she was pregnant. I feel like I'm just having sympathy pains for her. Or I could possibly be pregnant. But I'm not ready to be a mom yet. I am still a freshman in college, barely got married, and also got a new job. I've been thinking it was the flu but now I'm just not so sure. What should I do??? I don't want to go to the doctor and then find out that it's just sympathy pains. Because then I'd feel awkward. And sad because tinue wants me to have a baby with her.
