Should I finally test???

Basically I'm fed up of getting my hopes up to have them smashed again, so we decided to chill out with ttc be more relaxed with it. We did have sex the day after my predicted ovulation and never thought anything of it because I had a light bleed a week or so later that lasted around 4 days and ended very mucusy. This past week I've been having cramps in my lower tummy as though I need a poo sorry tmi, although I don't I've had tender nipples and headaches to go with it all I've been bloated this past week. Should I test??

AF isn't due until 19th
