Hope this isn’t a stupid question?!

J x • 4 year TTC journey✨ Ectopic surgery & tube removal Dec 21🥺 Successful 1st round of IVF. Pregnant with my little miracle due April 2023👶🏼❤️

Every time we have sex and my husband pulls out, I feel like all the cum just comes straight out!! He even tries to stay in the position for a while afterwards to prevent it from happening but it still all runs out every time. Is this why I’m not getting pregnant? How can I stop this happening? Any tips xx
