Just A Tad Bit Confused 😕

My husband and I are trying to have a baby of course . I ovulated on the 25th of April. We had sex 04/21, 04/23, and 04/24(we were trying to hold off until the 25th to have sex but we couldn’t lol) . My predicted period is supposed to be tomorrow 05/09 but I’ve been feeling weird lately . A couple days after ovulation I began to start cramping all the up until now . I normally don’t start having “period” cramps until the day before or the day of my period. From time to time I get headaches on the norm but alongside the cramping, I’ve been having headaches pretty often. Also, my body has been sore(mainly my back). I also found it weird that I’ve been waking up hot out of my sleep, which I normally do not do. Normally I can feel when my period is about to come on, but it doesn’t seem like it will...plus I haven’t gotten any of my period bumps(acne) yet. When should I take a pregnancy test? And could these be signs of pregnancy 👀👀 please help!!!
