ways to tell if you're pregnant without a test?

i can't afford one just yet, and can't afford to get to doctors yet, be a few week before i can. but i'm throwing up, haven't had a period in months (isn't unusual for me, PCOS) i'm either too hot or too cold. i lost a lot of weight and now i'm putting it on. i'm also really broody, like i was with my first. please note if i am, i will be able to afford to care for it, the reason why i can't afford a test right now is because my bf did a short week last week at work for dental treatment.

how many times as a female have you said, I think i'm pregnant? And not be. Since not getting your period regularly, it could some hormonal changes going on and perhaps your about it to get your period. There are a lot of symptoms you may have with pregnancy that mimic other things, so you need a test. I didn't any symptoms with my first child and with my second i had them all...(he is 8wks btw) lol Good Luck
