Possible implementation bleeding? SORRY IF TMI

Monica

So my husband and I have been TTC for the past 6 months. Yesterday I had a bit of very dark discharge on my panties. & later in the evening I had mild cramping.

Then last night after Intercourse I had bright red spotting. Thinking I started my period I put a pad on. But this morning the pad was completely clean.

Not sure if I'm just about to start my period or is this implementation bleeding.
