I was meant to start my period on the 3rd of February (my last period was 4th of January ish) it's now the 19th February and I'm still waiting for to start but all I keep getting is lower stomach pain ,every night when I'm lying in bed. I took a test on Tuesday 16th and it was negative ,I have been off my pill since A week before Christmas so my periods should be regular now. I don't wanna go to the doctors so I was wondering if people could give me some reasons on why or if I still could be or something?
