hello all, please can you advise?

i am on the pill, with a 7 day window for periods, but i have to admit i am not the most regular person, and when i was away for a week with my partner, i forgot to take them for most of the holiday. he is now in Afganistan and has been for 4 weeks, (he is a solider) and i have been having cramps, sore breasts, back ache, mood swings, im dieting and gyming but i am seem to be developing a pouch/bloated tummy!! so i took a test to check, and it came back negative. i took one a few days later and still negative. last night i had light brown spotting, and today in work i found had like dark dark brown patch on my knickers.

i am due my period now anyway so i was expecting blood, but not dark blood like this. am i pregnant? should i stop taking my pill? i am going to see a doctor when i can, but im so excited to be, but i dont want to get my hopes up or his, especially whilst he is away.

 

please help

Babs xx
