Actually last October 1st he came home, we had good relationship(intercourse) I got my period on October 15 to 20th.. He left home town and gone to job in November 7th. Till that we had good relationship(intercourse).My period is due on November 15th 2015. But I didn't get my period till 25th and on 26th I got light brown spot discharge and it gone and again today on 28th I got light brown colour on and off bleeding for 3 times..I got symptom like light stomach cramps, headache, tierd, gasteric prob. Only sleeping on sides, can't lay at my back. I tested on November 16th, 22nd and 26th, all came negative. Pls advise, now there is no bleeding but I fear alot and am always going to toilet to check whether I got my period. I want to get pregnant. Shall I wait for some more weeks and check or go for blood test. Please help.
