Confused

I took my IUD out March 31st, while I was on my period, after having it for 2 years and having a regular period every month. 28 days later, April 25, I got my regular period. I ovulated May 8th, according to several ovulation calendars, and me and my fiancé had sex May 8th because we have been TTC. Here it is June 1st and I haven’t had a period since April 25th. I took 3 hpt last week, all negative!!! I’m so very confused and frustrated. I don’t know if I’m pregnant. I don’t know if my period is off although it’s been so regular, even the month after taking it out. I don’t know if I took the pregnancy test too early, seeing I’m only 8 days late. I just want a positive test or my period, I just want a definitive answer already!!!!
