advice about sex and ttc

Ok so maybe i am being a bit of a worry wort because i just want to hear other experiences. Me and my husband have been ttc for 4 month this month we decied to stop tracking we just going to enjoy eachother and out lives and if it happens it happens. call women intuition or whatever i really was thinging this whole month anout ttc til yeasterday something came and i feel that this I dont share this feeling with anoyone mine worng. but i want to be safe in cause. does think having sex during implantion or the embryo is newly planted is bad or can cause anything negative. also should stop using sex toy til i find out or should forget about it for now and keep doing everything because their nothing to worry about
