Blood after ovulation a week before period

I have been ttc for 3 years now, my husband has vericosel and won't get the procedure done. I think because he is having to come to the conclusion he needs the help. Anyways, we have stayed active since the doc said it's a low chance but to him it's a chance to conceive. My question is anyone else going through this tough situation. Is it possible to have implant bleeding or should I consult a doctor asap?
