Veins

so I have been ttc I ovulated on 21st of this month, I have a donation on 19th and 21st, both times using concieveplus and soft cups, I noticed recently my breath have become very sore And heavy, they have gone a lot bigger and have blue prominent veins through them. I have constantly been bloated and have had period pains my period is not due for a week however I have had these symptoms for the last 4 or so days. I’m just wondering if anyone else has experienced this and had a positive???
