Possibly Pregnancy. Please Read and offer any advice

So this is is going to be a long description but I'm coming to you ladies. So usually this app has been about a week to 4 days off. So I'd start early according to my app. But I am trying to give it the benefit of the doubt that it's right finally. If so I'm suppose to start tomorrow but with my symptoms I feel like I won't be starting. List of symptoms.

Neausa. Especially after eating.

Swollen and tender breasts. So bad I can't walk around without a bra and my nipples are extremely swollen. Can post photos for you ladies if you wanna see what I mean.

Fatigue/constantly wanting to sleep

My dogs have been attached to my side lately

I gag when I brush my teeth (I do not have a gag reflux at all ussually)

Been crying over stupid stuff

Cramping but not normal period cramps it's like a sharp pain? Really hard to explain

Bloated

Now I did take a pregnancy test yesterday morning but it was a BFN.

The other issue is I could be like my mother whom had to get a blood test to actually confirm she was pregnant. Only ol1 out of 3 kids did she get a positive home test and I guess it was an expensive brand but she doesn't remember which one.

If I don't start by Sunday and a home test still comes out negative I will be going into the clinic to get a blood test done. Just wanna know your thoughts and maybe get a little baby dust my way ♡ thanks guys!
