Ok Ladies! Any advice can help!

Sorry on advanced if this is long... But here's a little back story.. I've always had an irregular period and conceived my daughter 4 years ago. Had a chemical 2 years ago, still with irregular periods.. So I believe there's always hope.. Anyway, for the past 2 weeks or so I've been feeling so strange! It started by getting dizzy and lightheaded for no reason, then came the cramps (mostly on my left side) then the nausea and heavy feeling boobs( not really sore, just heavy).. Now I seem to be getting sick, kinda like a sinus infection or something and I've also been feeling really wet down under(tmi) but not really seeing any discharge when I wipe.. I've taken 2 hpt and both BFN! I guess my question is, does it sound like ovulation or possible pregnancy and just tested too early?

PS I also feel like I'm starving all the time!
