Help bleeding

Ok so I just went to the bathroom and it was streaked pink kind of red. I'm so scared.. My BF and I are not on good terms due to the whole he changed his mind bs..... The only thing I could think of is I'm on two antibiotics ( I have an autoimmune system disease and I take immune system suppressants which in turns leaves able to get infections and they are hard to treat) I got a yeast infect I use Monistat and used the plastic applicator and I'm sure I bump my cervix the thing came back out so I pushed it up high... Idk I'm hoping it stops in the next few hours. I'm not cramping....
