What the heck is going on with me?

I need some help, and since you guys are such experts on this stuff I hope you can help me.
I had my beautiful baby boy 5 months ago. I had my period 9 weeks after I had him. I have had a couple more periods since then. Before I concieved him, I had 21 day cycles, but they had gone to 28 day cycles after having him.
Well, now I am late. Over a week actually. I have taken FIVE pregnancy tests at various times of the day over the last few days and all are negative. So, I'm not pregnant.
I have never in all my "period life" been late without being pregnant so I am a bit puzzled. I am not breastfeeding, so I can rule that out as a cause.
The things that were different this month are that at the beginning of my cycle I had the flu and right now I am battling a UTI that I am trying to get rid of naturally. I know they say that being sick can affect your period, but I can't ever remember that happening, so I just don't know.
Anyone experienced anything like this or have any insight?
TIA!

It's possible that the flu and the UTI delayed your ovulation. Without charting, it's impossible to know for sure.

And the hormonal shifts of pregnancy and birth have changed cycle patterns for a lot of women. I think it's entirely normal. I'd encourage you to start charting and figure out what is going on in your body, beyond just what day you are on your cycle. Even if you're incredibly regular, you can benefit from that knowledge!
