Help understanding

Ill try to make this short as possible

So i have a pretty good regular cycle been using premom ovulation test strips for like the last 9 mths or so anywhere from cd 12 thru maybe 15 ill start getting my positive peaks and so this cycle was a bit diff and i have both apps this one and premom and they seem both to be on point with my cds and the start of af every month so as am checking both apps say my fertile window was june 8 thur 13 so i started testing between those days and was getting low readings so i thought maybe i had missed it so i waited about another day or so and noticed on cd 18 i got my positive so am thinking to myself maybe this is just an late ovulation happening

But another thing i noticed that during that so called fertile window i had the lightest pinkish color after wiping from using the rr and from there on i have been feeling some what bloated and after that positive ovulation test been feeling very dizzy and a few times i felt like throwing up or nausea so that is what confusing me is that i thought these ttpe of symptoms happen like days after ovulation but idk just if anyone can help me understand or has gone through this give me some insight on what could be happening because i been gooling and watching youtube vids and nothing is helping
