Sex before/after implantation?

Question

Does it matter if you have sex after your fertile window before possible implantation? Like am I going to mess up implantation if I have sex? 
I had a MC and when I called the doctor to say I had bleeding... she asked if I had had sex within 24 hours?
What do you all do if you’re TTC/early in pregnancy?

Answer

Sex doesn’t have anything to do with implantation

Answer

Use opks and temp to confirm ovulation and you will have accuracy. You should have sex in your fertile window before ovulation and a few days after. It shouldn’t affect implantation. Sorry about mc. Have you had cd 21 blood work done like progesterone and lupus antibodies you could need progesterone and or baby aspirin talk to your doc.
