help needed

Just looking for some advice/reassurance/similar experiences!
Been Ttc for a while. This month had a tonne of sex around ovulation time (around the 9th).
Since then I have started to get loads of symptoms: nausea every day, really tired, peeing a lot more, huge appetite, extremely emotional (like sometimes feel like crying for no reason at all all of a sudden) and mega breast changes (they are huge!! Dont fit in my bras, veiny, huge nipples(!) and so heavy).
I usually get some symptoms round TOM, but not like this. However, I got what seems to be a perod on Thursday. Some fam are saying I should still test. Have a doc appointment next week. Im just totally overwhelmed with everything and dont know whats going on with my body at all 😔 any words of wisdom?
