No idea what is going on... advice please!

[char97xo]

So my periods aren't on time every month but on average they are about 30 day cycles. The longest I have gone is 36. However, I am now at cycle day 38.

I have been having nausea for the last 10/11 days, I keep getting feelings every couple of days like my period is coming - twinges, dull aches, cramps, - but nothing happens. I have tested a couple of times and from what I can see, they are negative.

I just have no idea what is going on right now and I think that it is the not knowing that is the hardest part! I would rather either get a positive or get my period and just know what is happening. Any advice or comments would be greatly appreciated. TIA

Negative tests would show you're not pregnant, have you been tested for Covid? That's affected a lot of women's period cycles as a little reported side effect

No, I had my first vaccine last weekend which I assumed was why I was nauseous probably out of nerves cause it started a couple of days before and nausea is a side effect of the vaccine as well but it hasn't been going away. It's just strange as I don't normally feel like this at all.

Do you know when you ovulated? If you ovulated later for any reason (maybe the vaccine for example) your period would be delayed by the same amount of time.
