curious lang kailang nabuo si baby?

Hi mommies, curious lang. 33 weeks pregnant here. Kailan po kaya naconceived or nabuo si baby? May tracker kasi ako ng mens and sexual intercourse namin ni hubby. LMP:July 11,2019 3 days lang lagi tumatagal. And 28 days cycle. EDD: April 16, 2020 NagDO kami ni Hubby July 13, 14, 27 and Aug 2 unprotected and non-withdrawal. Then July 29 with condom. Kailan po kaya nabuo si baby? August 8 expected kong may mens ako pero August 10 nagstar na ako magPT and August 12 parehas positive. Thank you po sa sasagot.
