Just A Little Nervous

So I’m supposed to be on my period. My boobs are swollen and are incredibly sore, I feel very slight cramps, I’m bloating real easily, hungry constantly and I just feel tired all the time as well as moody. Now I’ve always had an irregular period, but nothing major, only off by a few weeks. I have been wanting to start trying for kids so I had sex during my fertile days. I’ve been told I should wait at least 5-7 days after my expect period start date. So far it’s been 3 days including today. I’ve noticed I feel a bit queasy from time to time but nothing major. I would just brush it off but even though my boobs hurt they also feel amazing when my husband grabs them and my nipples feel and look a little different...I dunno, I’m slightly obsessing a little. Anyways am I just overthinking it? Should I still wait to take a test?
