Sign or coincidence?

Unfortunately the blood pressure medicine has not been helping my breastfeeding issues. I stopped taking it yesterday. I am still hanging in there with the pumping, even though it is difficult. This afternoon, I went to get the mail and in my mailbox was a random, full-size container of Enfamil Premium sent to us as a free sample. I laughed when I saw it, but asked myself if God was really blatantly trying to give me a sign, or if it was just a funny coincidence. I haven't decided for sure yet.
