Help! Maybe or no ?? Advice needed

What do u guys think , I pretty sure glow has my ovulation days wrong ... two days after my period , I had spotting it was very very little and light pick happened for half of the day. And now like 1 week ago I was feeling very nauseas and tend boobs and lots of gas lol and one meeting I'll be hungry eating something but then lose apatite and not even want to look at what I'm eating cuz I would feel sick , been very emotional ... I have never had spotting after my period before and I mean never . So what do you guys think it could be . I haven't had my period yet . But got a headache out of the blue so I'm just confused 🤷🏻‍♀️ oh also been having really bad heart burn and acid reflex
