Pregnant or PMS? Irregular periods, so I don't know!?

I have irregular periods - my last menstrual cycle ended on May 10th & I tried to figure out my ovulation date by checking my cervical mucus on a daily basis. I thought I had the ewcm on 05/27 - which I had sex with my husband on that date and the days around it. Last week before I was going to test I got a urinary tract infection and noticed that i again had discharge that looked like i was ovulating, it really confused me. After the worst UTI of my life was finally over, I now get headaches everyday, throw up after brushing my teeth, wake up several times in the night for water, I have extremely sore boobs on the sides and all around, hungry all the time & dehydrated & still no period. I don't want to test & be let down if this is just more PMS, I have been taking Vitex to regulate my period & PreSeed to help us get pregnant, this is our first month actively trying - before that we were trying, but not charting or anything for a year and a half, so I am super confused. Anyone have any advice?
