Hi ladies! My name is Suzanne an I have 3 wonderful kids who I love dearly but in the beginning of March I had a chemical pregnancy

we are ntnp I guess since I am not on the pill or anything. I was just wondering how long it took your cycle to come back. On 3/5 my hcg level was 0 therefore not pregnant anymore. I bled an spotting off an on for that week. Now I am like cd 39 an no sign of AF. I would think since my levels went down quickly my cycle would return quickly also. I do not think I am pg since hubby was admitted in the hospital 10 days after I had the chemical pg an was there for 2 weeks then come back home for about another week then was back at the hospital for another 5 days. I know stress can effect everything but really I would think that she would have showed up by now. I took at pg test a couple of days after my period was expected an it was negative. Any ideas as to what is taking her so long to show up?
