Hello there, well first there is a few questions for u? Is ur period always like that? Do u have ur period every month? For how long have u been tryin to get pregnant?if ur period is irregular ovulation is probrably not takin place, that's what happen to me, I had spottin for a few days and sometimes my regular period would come right after and sometimes It just wouldn't come at all,I'm still tryin to get pregnant,but I found out that my irregular periods was a simptom of pcos, and I didn't ovulate at all, I started takin some pills that it was suppost to help me ovulate, it didn't work for me so I'm going for a stronger treatment now, but I've seen and I have friends that after 3 or 2 years trying got pregnant wit only a small dose of clomid, wich it makes u more fertil and estimulates ovulation. Good luck to u and I hope this is helpful to u.
