Anyone puke before period?

I have two under two.

My iud fell out in October. We’ve been super, super careful. In fact we have rarely had sex because I’m so worried about being pregnant. My husband is scheduled to get a vasectomy next month.

I had hg with both kids.

Today I should have started my period.

I’m 10months pp.

pregnancy tests have been negative.

But, I’m puking like I did when I was pregnant. No fever, but, the nausea comes in waves like hg one minute I’ll be ok the next I’m puking 5-6 times.

Please, please tell me I’m probably just experiencing some weird period thing. Tell me it happened to you. I don’t think I can be this sick again. pregnancy doesn’t work with me.
