15 month of trying, two miscarriages and then.....

My husband and I have been trying to conceive for 15 months and have had two miscarriages in that time. Im only 9 DPO and I’m never one to test early but I was feel so weird this morning. I felt like AF was coming early, I was so crampy and my breast’s really hurt. I’m not going crazy right?? There is definitely a second line?
