Sorry if I’m being thick but my lmp was 4th April. I had sex on the 6th (yes I was still on!!) period lasted 4 days. I then didn’t have sex again for a couple of weeks. When would I have conceived?? I’m 11 weeks weds going by the date of my last monthly period. Surely it has to be after having it on the 6th?? I did have it a couple of times 🤣🤣
