Whats happening

So my boyfriend and I made out

I gave him a blow job I spat most of it out we kissed and 10 mins later he went down on me

All this happened three days after my period

A week later I took a pregnancy test using an HCG strip that uses blood instead of urine and it came negative

Glo said i was gonna ovulate on the 30 of last month

But I didn't see my usual raw egg white discharge

I saw watery milky discharge

That lasted till 5 days

Today being the sixth day I saw watery milky discharge mixed with lots of raw egg like discharge

But now my breasts feel sore

What is going on please
