Help me pleaseee my period is lateee

Alyssa

So my period are usually around the same time and always 5 days. My last period was feb 5th-9th and i did have unprotected sex during the following weeks after but not since it’s been March. I haven’t felt very sick or anything just a little nauseous for a short amount of time and a headache or my back will ache here and there. But I’ve been needing to pee a lot and I’ve been having discharge had been creamy and I’ll get it a few times a day or so. March 10th i took a test but it was negative and i don’t know if i could even be pregnant by now still or what’s happening with my body.... i could really use some advice lol
