I have been trying to conceive.I stopped birth control pills.I have spotting.Please help.

Hello doctor,

• I have been trying to conceive since 9/11/2014, which is when I stopped birth control pills and started prenatal vitamins.

• My cycles before BCP (Birth Control Pills) were always regular, about 30 days +/- 1 day with a 7 day period.

• And on BCP, my cycles were always 28 days, with a 5 day period.

• When I stopped BCP, I had a 5 day period, which began my first cycle of 31 days.

• The next cycle began with a 6 day period and the cycle lasted 37 days.

• Then this current cycle, which began with a four day period, a bit lighter than normal.

• I am currently on CD 27 and I believe I ovulated 3-4 days ago.

• So, the problem here is that I start spotting on CD 25, along with light cramping.

• It was only a very little bit of light brown blood, so I did not think much of it.

• Yesterday, CD 26, I had a little more throughout the day, then quite a bit right before bed.

• This morning, I am still spotting but much heavier than the past two days, and am starting to get a little alarmed by this.

• The blood is still brown. Any ideas on why this is happening, presumably 3-4 days past ovulation?

• Is this cause for concern? I have never spotted ever before.

• Also, I started taking Vitex at the beginning of this cycle in hopes of shortening my cycle a bit.

Thank you in advance for any advice.
