New to pregnancy and ttc

Kay
Hello everyone, I have been tracking my period and ovulation days using this app for a few months now. We have sex on the highest days, but so far I haven't become pregnant yet. I just had sex twice during ovulation which was about a week ago now. I've had sore breasts, especially my nipples. Not just the usual sore, but so sore that even moving my bra or anything hurts them. I've had a few sick spells but nothing too major. I took a pregnancy test last night, but it was negative. Is there a certain time I need to wait to take the test? I'd taken the dollar general brand, just because I've bought so many expensive ones before only to get a negative. I'm hoping this time is my time, but I'm trying not to get my hopes up. I'm not sure if I took the test too early or what? And could I even be having sore breasts this early? I never usually get sore breasts during or after ovulation so it's new to me. And it's never happened before so of course my mind jumps to hoping this time is my chance. Thanks for reading :)
