anyone have thoughts or experiences?!

I need some advice the 2 weeks or so I've been eating everything and craving foods I usually don't, and then I've had times Even the thought or seeing food makes me want to run to the bathroom and puke. I puked last week and kept feeling like I had to at weird times for no apparent reasons and thought I just had a stomach virus but it keeps going on and off I'll get pains and menstrual like cramps. I'll also be constipated and can't go for days... I've been peeing like crazy too. I didn't take a pregnancy test yet because I usually get my period with in the 1st or 2nd  week of the month. I just want some advice to see what someone else thinks. My boyfriend keeps telling me I'm pregnant but I don't think because I was just told not long ago I have pcos syndrome and it will likely be pretty hard to get pregnant. Just don't know what to think and wanted to see if anyone who was or is actually pregnant went through all this at all... thanks in advance ladies 😘
