What's your opinion

Hey!

Me and my SO haven't been trying but haven't been preventing getting pregnant, so this month we decided to go ahead and try. Towards the end of August I picked up some Folic acid I take 800mg a day I picked up some Cheap ovulation test and I took my first one yesterday and it was negative but I ended up BDing because my SO went out of town then today I took another one and IM OVULATING!!! So my question is how likely am I took get pregnant from sex the day before ovulation?

Any success stories with folic acid?

Or successful pregnancy from sex the day before ovulation?

Thank You!
