Have been TTC since a miscarriage in March.
AF always comes on day 26 of my cycle, when no AF turned up on day 26 of this cycle I did a test- BFN 
Then on day 28 I get pains (v low in my stomach rather than my back which is where I usually get period pain) plus 4 days of bleeding. Lighter than normal period and brown (sorry TMI) but still a lot heavier than the implantation bleeding I had with my last 2 pregnancies.
Think nothing more about it but have been feeling very sick so did a test this morning (day 36) and got a BFP (vv strong line)
WTF is going on
?!
Should I go to see the Dr on Monday or just wait another week and test again?
