TTC after miscarriage

Hi, I’m trying to conceive after having a miscarriage in April. I think it had a lot to do with taking plan B but who knows. Got positive on 3/29 but started bleeding & bled up until around 4/15 & got hcg beta down below 5, on 4/20. Started trying again, the following week & maybe it was too soon but my period started 5/18 & I was disappointed & very sad but it lasted it’s usual 5 days was just slightly heavier & more cramping. So after I just told myself that it was just my body’s way of getting that final cleaning before I get pregnant again. So I’m back at ttc, I am about 1/2 dpo & I haven’t felt my ovulation cramping like I usually do but my boobs are sore. I’m very nervous that it won’t happen this time either. What are your thoughts or opinions on ttc after miscarriage? Too soon or No?
