BFP month after MC

Laura • 2 lovely children ttc #3. Had 2 MC this year so far.
I had a chemical pregnancy at 5 weeks last month I have BD'd twice after that and been waiting for AF to appear I've been told it could take weeks but this morning got a BFP very nervous and checking myself everytime I go to the toilet. Did anyone else get caught month after and did you experience any issues through the pregnancy??
