Advice

Hey guys, I just wanted to get some advice. So I am on a progesterone only pill, I have been on this pill for a month now. I was on the combined then had a period and got put straight on to progesterone only so I did have the 7 day break. Today I have felt really tired, sick and lightheaded. I am really bloated, I have loads of discharge and my boobs are so sore especially round the side of my boob and my nipples. I have been getting lower belly pain and vaginal pain to. My stomach feels really heavy. I am 5 days late on my period so I was just wondering if anyone thinks I should take a test? Also to note with the progesterone only pill there is a 12 hour gap and I have missed some pills by 2/3 hours just because these pills are new to me and I’m always forgetting and sorry if this is TMI but I have been having sex with my partner with no condom and he has been ejaculating inside of me. I just need some help!
