36 days late and FREAKING OUT

I’m trying to get pregnant for about 3 months now. My period was definitely always on time and was super regular but ever since we started trying, my period has been out of whack and now my period is 36 days late. How convenient, right?

Did a pregnancy test about 5 days ago and it was a big fat negative... I ordered some fertility pills online and they should be in tomorrow... is there a chance I can still be pregnant?

I’ve actually been having allllllll the symptoms like I have been gagging, feeling nauseous and I’m super tired always... but the tests keep coming back negative. Any word of advice ??
