Help!

I’ve been taking these ovulation tests the last couple days, on Premom the middle one came up as peak, other two were high, (all same urine sample) I used the easy home test. Few questions, how long do I have at a peak to have sex with hopes to conceive? And are there any other ovulation tests I should use that are more accurate? I’m new to this! We were pregnant and had a missed miscarriage at 11 weeks, so now we want to try in hopes of falling pregnant again and carrying our rainbow baby! Any information or guide is so appreciated 🌈🌈🌈🤞🏼🤞🏼
