Confused

So I got my iud removed the beginning of September . I had with draw bleeding after for a few days . Then the beginning October I had a period a few days after I stoped bleeding o started testing with opks... last night I had a test that was almost positive and then this morning it was positive. I did have sex last night but today I been having ewcm with blood . I’m very confused as to why I’m bleeding . I’m starting to get frustrated . I feel like my cycles are all over the place. So far I haven’t bleed enough to put a tampon or a pad on . It’s mainly just when I wipe but it’s obviously there 🤦🏻‍♀️🤦🏻‍♀️
