trying to conceive

good day . I am 29 years of age I have 1 daughter 8years .I have been trying to conceive since 2007 so far I have had 3 miscarriages all at less than 12 weeks . I last miscarried on the 8 april and since then m still trying but it seems as if m doing nothing
I had been booked for a lap and dye then I got pregnant when I got the last miscarriage. I have been tracking my mense since october 2011. Well in Oct I menstruated on the 5th ,nov13 and dec 19.now on the 12 of this month. I had this brown drop and it only showed on my pantyliner. Now today I noticed bright red drop when bathing .can anyone make sense of what is really happening. Sorry m new to the forum if my story is too long
