Evap or too early to tell? HELP!

Lauren

On 4/5 I started spotting, it's now 4/16 and 11 days of still spotting. My period was supposed to start today on 4/16 but it's not heavy, still spotting. My periods are normally really heavy!! Like extremely heavy! I took 2 test on 4/14 & they came back "positive" a little after an hour after I took them. (Test are different brands) could they be evap lines or is it too early to tell. I am 12 DPO as of today, I was 10 DPO when I took the tests.

I have had a few other symptoms besides the spotting. Headache, increased appetite.

Also, if the spotting is implantation bleeding, could you have a period right after?

Thank you!!
