Okay so on Thursday and Friday my ovulation tests were super dark and positive ! 
I had sex Thursday and Friday and all week previous to the positive test - I didn't have sex yesterday -( will I still have a chance of getting pregnant?) 
Also I went to the toilet two minutes ago and I wiped the smallest amount of pink blood ? What does this mean ? 
Is there a high chance of pregnancy if I didn't have sex yesterday but did all week last week and on my positive test days ? And if I do it tonight too? Help !
