possibly pregnant again 😅🙈😌

so im 5 week pp. stopped bleeding at 3 weeks and had sex for the 1st time but since iv had sex about 5/6 more times using the pull out method (i know i know not very effective lol) so i know there is a very good chance i may be pregnant. what im wondering is does anyone know if 5 weeks pp is too early to get my period back as since xmas day iv had the most lightest period hardly enough for a pad even. im worrying as i had this kind of bleeding for the first 10 weeks of my last pregnancy and it was put down to implantation bleeding. its brown blood not bright red and very light where my periods are normally quite heavy. raly greatful if anyone can offer an opinion 😁
