Hopeless

Been trying to conceive for the big NINE MONTHS now. We've tried every month even not around the time of ovulation. I'm starting to get hopeless and I have 3 days until AF and I feel if she comes I'll be a wreck. I seem pretty sure about this time. The other day I woke up w nausea and couldn't even walk. I also got so dizzy I randomly almost fell over while walking. Other signs have came to, like a bunch of random migraines, stomach cramps, and I THINK I HAD INPLANTATION BLEEDING. I spotted 10 days after trying to conceive around my ovulation day ( the day before the 33% ) I just feel like either these signs are being made up in my head or there real and I'm just freaking out. I just need help and support. I want this to be it! I've had other signs and can't think of them atm, and oh BAD MEMORY LOSS. If that helps. Pregnant or not? Support?
