6 days late, bfn, nauseous and dizzy...

Cervix is high and closed tight. Showing severe pregnancy symptoms but getting negative test. Not sure when I ovulated but I don't think I ovulated when the app says I should have.

Was trying for a baby bc he wanted another one. I was on the fence. Now we live together but we are not together. He became verbally abusive and I am waiting on an opening to come up for an apartment for my kids and I.

So what do i do? I dont want to keep buying tests just for them to be all negative. I called my dr bc ive never late like this in my life but I had to leave a voicemail and i havent heard back.
