I had a weird period, started off spotting pink (it usually starts off brown!) then had a day of medium flow and mild cramps and then it eased off so all in all about 3 days? Now I’ve been spotting pink blood for 2 days straight with no sign of stopping?

Should I take a pregnancy test? Or am I being naive? I have some mild cramping/stretchy pully feeling in my lower stomach and my other half’s smell all the sudden is so unappealing to me, I feel like I could live off sugar and food is so disgusting to me, what are the chances I could be pregnant?
