TTC after misscariage

Hi,
My partner and I are trying for our first baby. We had a misscariage in June and were told to wait a cycle before trying again - that's what we did.

My cycle is irregular so it is hard to know when I am ovulating. We are intimate every other day to give us more chance to conceive. My question is IF there was fertilisation, is it dangerous to have intercourse before implantation?

Thanks.
