Hi there, so I had protected sex about 11 days before my next expected period. I experienced cramping, acne, bloating, all of my usual symptoms about two days prior to my expected start date. Then my symptoms stopped, and my period didn't start when expected. I took a pregnancy test on the expected day and it showed negative. My period started the next night but only spotting, and now the next day when I would normally be bleeding heavily I am experiencing only light spotting and heavy cramping. I am not currently using birth control, is this just a hormonal period slip? I'm concerned because my period is very regular every month. Any feedback is appreciated, thanks!
