Advice please!!

Last month May 14 I had a miscarriage (I didn’t know I was pregnant until the bleeding went on longer than my usual period and I took multiple hpt) anyways I bled until May 31st for about 2.5 weeks. I’ve been sexually active since I stopped bleeding. Today I was supposed to get my period but it hasn’t came. Does that mean it’s going to take some time for my periods to go back to normal since having a miscarriage or is it a possibility I could be pregnant again or would it be too soon to be pregnant right after a miscarriage?
