Struggling TTC

I just got my period yesterday so I'm feeling really down that we are not pregnant...yet again. My partner and I had sex every second day on and before when I would have ovulated so I'm really bummed we've missed out again.

Although, my period usually gets heavier and really bad cramps around day 2 and at the moment it's still really light, and I've had no cramps. Could this be implantation bleeding perhaps? Or am I just really wishful thinking? 😭🙏🏼
