Questions....

Hello everyone,
I'm sorry if this ends up longer than it should be... So we've been ttc for a little over a year, I decided to try opk so when I got them in (July 12) I started testing a few days later just to get used to them and reading them. All my apps said ovulation would be August 1st. I got a VERY positive opk on July 22. AF isn't due until August 16 (irregular) so this week haven't been feeling quite right since Sunday, after work I took a HPT, it was very faint but was there... I want to wait a few days before testing again and not getting my hopes up. Has anyone every had a similar situation? How long did you wait to test again to know for sure? This week my stomach has been bothering me, I've had lower back pain, some very light cramping (doesn't seem like AF cramps) and aversions from certain foods and drinks I love (like coffee) thank you for any advice!!! :)
