I'm terrified I might be pregnant again

There is possibility I might be pregnant again. I had a miscarriage in April, which was a planned pregnancy and I didn't feel ready for another baby yet because the miscarriage broke my heart. I haven't been on this app in a while because I stopped tracking everything. I only signed on to see my fertile week and log my period. I waited to have sex the day after my ovulation thinking it would be fine.

Well now my period is late (only a day), which isn't my biggest concern. What has me concerned is I'm extremely sensitive to smells today and my son pooped today and the smell alone had me vomiting everything I ate. I know throwing up isn't normal for me and something has to be up.

Went to Walmart and bought a test but I'm honestly too nervous to take it. Ugh.

If I am pregnant again, I'm terrified I'll have another miscarriage. I can't go through it again. It was too painful physically and emotionally.
