Trying to get pregnant 🤰

Hello I am 21 years old been with my fiancé for 5 years now will be married September 30th 2018 💍🙌🏼

Anyway... I have been trying to get pregnant the past year and would like some advice. After having sex I sit still occupy myself to not use the bathroom. (Yes he finished inside me)

I catalog every time we have sex. We had sex July 15th and I ended up spotting slightly the 18th-19th. My cycle was due August 3rd and it has not arrived! (Thank god)

I’ll be waiting a week or so to test to assure things will show up.. but if it’s negative... what else can I do? We have sex almost every day of ovulation.. sometimes not... like last month as seen below 👇🏼
