Symptoms before positive test ?

I’m 11 dpo. (Tracked with opk but not bbt)

I was eating breakfast this morning and my eggs tasted like soap. I asked my family if the eggs tasted funny and they said no.

I thought it was weird so I googled it and apparently it’s a possible symptom.

I’ve heard of metallic taste but not soap.

I took a test and it was negative.

I know it’s possible that it could be non pregnancy related but I was wondering if anyone had symptoms before a positive test ?

I get all the symptoms with my period. Sore boobs, backache, bloated, etc. so I don’t try to watch for those because it’s normal for me to have these symptoms but the soap taste really threw me off this morning.
