Pregnant?

I got off birth control October 18th, since then my husband and I have done nothing to prevent it (if it happen it happens mind set).

Last week I thought i got my period, but I ended up only spotting for like a day and a half. I have had several pimples come up on my boobs within a matter of days (which isnt normal for me), also they’ve become super itchy. I feel like I’m never full, no matter how much I eat. And the past few days I’ve had hella heartburn.

*I took a test but it came back negative. Should I retest later? Or does it even sound like i could possibly be pregnant?
