Just wondering

Barb
Does anyone else get the sick feeling of smells when their period is coming? 
The reason I'm asking I feel different than I usually do with my period but I took a test this morning and it came back negative which really ain't a surprise for me. 
I got my period today but I'm also on bc cuz I don't get my period if I'm not on it but last month I missed a pill before my period and than missed a pill 2 days after I started takin them after my week of no pills.
