Pregnant?????

I ovulated 12 days ago. My boyfriend and I had sex without protection.

I took a test on the 11/28 and it was a big fat negative.

But I noticed my right nipple is SO SORE like i cannot touch it it’s so sore. My left, totally fine.

I decided to test again today and it was a negative also.

I’m noticing my tastebuds are different, and oh my god. the smell. I’m a CNA and usually I can handle smell... but oh god...

Am I testing too early?? I’m younger and have no parental support in anything and have been living on my own since 17. I need advice.
