Cold or...?

Husband and I have been ttc for our 1st for 2 yrs. AF came on the 8th, exactly as expected. But it was abnormally heavy for me and only lasted 2 days then only showed up a little when I wiped. The 9th I was stuck in bed extremely dizzy and tired, a week later and I still feel the same only I've thrown up in my mouth a couple of times, I've had headaches for the last 4 days, gassy ?, and tonight my stomach is a little upset. I've had some sniffling, sneezing and congestion but nothing crazy like a bad cold. I feel warm but don't have a high temp. Not to sure if it could be summed up to just a cold or something more. Never recalled feeling this dizzy and tired for this long with any other cold. I'd rather not do a hpt unless it's sounds somewhat promising. Any advice? Thank you!
