Advice please

So I tracked my ovulation this month....9DPO my period came, much to my frustration. Had a word with myself and decided to focus on trying to sort my cycle out, healthy vitamins etc to making TTC a little easier. However, 3 days later and I’m in quite a lot of discomfort with bad cramps...and have also been feeling nauseous, dizzy and light headed at time. I’m wondering if I’ve had a miscarriage? Should I test to see if I get a positive to make sure I’m not having an ectopic pregnancy? I’m worried about contacting GP as I’m probably overthinking but I’m just really confused as to what is happening with my body atm. Any advice would be really appreciated. Has anybody had anything similar?
