Help? TMI

I had sex on March 3rd&4th (days I got a positive ovulation test). On March 15th, I missed my period. My "period" came on March 31st. But it was just spotting that turned into a very light period, but I could've worn a panty liner the entire 7 DAYS. Usually my period is very* heavy and never late. Not to mention I usually have cramps& clots (sorry tmi) which didn't happen this time. Now, I have lots of discharge (again, sorry tmi). I took several test, even went to the health department two weeks ago to have a urine test done (even tho I wanted a blood test, they said they will not do a blood test). I am scared to test again because of the disappointment. I just can't shake the feeling that I am pregnant. I have tried to tell myself I'm not and I'm just imagining it, but I get nauseous and have been peeing a lot. If I am, I would be almost 8 weeks (on Sunday). Most of my tests were faint positives, as I even posted on here and a few of yall commented saying yall saw it as well.. I'm so confused.. please help.
