Possible TMI but I’m so lost and starting to worry...

So my period I think started on the 1st but it wasn’t a normal period for me. It was very spotty and would be light one day then normal flow the next then almost not there the day after etc. My periods are normally very heavy for two or three days. I was heavy on the 4th and 5th then nothing on the 6th.

Anyway... you can see in the photo below the two times I had sex. The 14th he didn’t get off but didn’t wear a condom. The 22cd he got off in me. I normally start my period the 1st or so of every month. I haven’t had a period yet this month but the pregnancy test I took on the 3rd was negative.

I have no idea what’s going on and because of covid-19 I can’t just get an appointment with the doctor. Any and all thoughts would be great cause having had a miscarriage previously I’m panicking a bit not knowing what’s going on.

Thanks!
