I’m in need of some help...

Ka

Last month I was late for my cycle and I took a test and a very faint line was there. So I took a couple more and they were negative. A few days after the negative tests I started my cycle and the symptoms I thought were from pregnancy was gone after my cycle so I thought maybe it was a false positive. Well I am currently 19 dpo and also late for my cycle. Should I take a test or should I just wait a little longer? My breasts are sore and a slight increase in appetite. That’s about the only symptoms I have at the moment. I really don’t have anyone that I can talk to about this and I’m in need of some advise. Can anyone help me?
