Vvvffl??

I'm having a bad day! Just found out my sister is expecting her second baby and I haven't even had my first yet. I've had multiple losses Nd this is my first round in Clomid. I'm DPO6 or DPO 7 I got a postive opk and then 5 hours later is was negative again noticeable very negative opk. I was told as soon as u ovulate opks go Negative. So I'm not sure what dpo I know its early I just need to test. I think I see a very faint line.
