Irregular period

This is the first irregular period I’ve had in 6 years so I need some help. I had all of my regular period symptoms, increased hunger, cramps that feel like tearing, sensitive skin, pimples, dreams, etc. but my period is now 7 days late.

I had covid during my last period and it made it super heavy for 10 days. I’m normally heavy for 2 days and light for 5.

I recovered from covid, and had sex with my boyfriend about 2 and a half weeks ago, the day after my fertile window was supposed to end which would have been about 15 days after the start of the 10 day period but now I’m not really sure when I ovulated. We used a condom and he pulled out and we checked the condom for holes. We had sex two other times later in the week again with a condom but he didn’t finish during sex

I just want to know what you guys think? My pms symptoms have pretty much gone away now which is concerning because my period hasn’t started. I know it’s not a great indicator but my cervix is get lower and more firm every day and my cm has gone from a whiteish color that I normally get before a period to clear. I have also been taking vitamin c the pst two days to help get my hormones back on track.

Any advice or similar experiences you can share would be great

Update: went to cvs first thing this morning to calm my nerves, got a pregnancy test and it was negative, checked after 2 and 10 minutes. Safe to say this is from covid or should I have waited longer to test?
