HELP!!! Does anyone see it

Shana
Ladies I need some help. AF was due Friday 4/22 I took an ept on Thursday 4/21 the top one which is blue came up very faint you can't really see it in the pic. I took another one Friday that's the pink. They both are positive. I'm not as excited as I should be seeing that DH & I have been trying for almost a yr. Friday night I started spotting, then yesterday morning it came heavier with little to no cramping. Took another test the blue on the bottom. It came up positive too. I'm not sure what to think anymore as I'm still bleeding. Should I be worried?? I've been reading to see what could be the cause & it could be anything. I'm leaning towards breakthrough bleeding. I'm trying to stay positive.
