Ovulation confusion??

Okay so I've been TTC for 4 months now I'm trying to get more in ture with my ovulation dates but on glow its telling me today is my highest ovulation day but when using test strips it's telling me I'm not ovulating? How can I tell? I plan to have an obscene about of sex this wknd with my partner just in case lol but this is sooo confusing!! Also does anyone actually lay still after sex and does it make it easier to conceive if u do or Is that just a myth?? X
