could i be pregnant?

okay i need a little advice! so i have been ttc for a little over 6 months so not too terrible, but i have been tracking all my periods and starting doing ovulation tests. according to glow i'm currently ovulating but when i look at the past months (all of which are identical number wise) i actually probably peeked the 24-26 and BD on the 24th and 26th.
today i got really sick, like threw up and have cramping and an upset stomach. which is really weird for me. any thoughts?
