I came off my pill at beginning of July and had a long bleed

It takes awhile for the body to adjust to the hormones again without the birth control which can delay your period and make it shorter or longer when it does appear, your body is preparing to have its period soon and shed its egg (the primary job of birth control is to not release eggs) so it is going to feel weird for awhile until you are used to it again.  If you are trying to conceive just wait until you have had 3 regular periods and then start to try by having sex as often as possible instead of getting up to clean yourself off right away, lay there 15 minutes to half hour and then get up this gives the sperm time to get to where they are going instead of falling out right away with gravity pulling them down.  Good luck and hope this helps
