I'm so lost . TMII

I had a very light period this month. I'm still cramping slightly  , also shorter than usual . I started spotting 10 days after ovulation . I didn't have a flow rather just spotting . Last month my AF was so heavy I had to use maternity pads . It's been 2 days since its gone yet my breast are getting larger and now I started to noticed bumps all around my nipples . My boobs hurt a lot , even when I have nothing on . My nipples have a tangling sensation . I tested yesterday with a cheapie and BTN . Is anyone else experiencing this ? Has anyone gotten thru this that can share some light ? Thanks in advance
