I know that science tells us it doesn’t matter what you do right after sex, but my girlfriend (who is 36 and pregnant with #2) told me that she got pregnant after taking her friend’s advice - a mom of 4 - to put her heels up on the bed frame and tilt yourself up so that you’re basically upside down for a minute or two after sex. My OB happened to mention how many patients she’s had who got pregnant while doing that. I followed suit this round and am pregnant (here’s hoping for a sticky bean!) now too. It may all be correlation rather than causation but it certainly can’t hurt. Good luck, all!
