Nervous to test

I'm nervous to test. I had my son in November, and I'm having symptoms similar to when I was pregnant with him. Tomorrow will be two days until my predicted period. Scared to test. I've been trying to also bring back my milk supply because I stopped breastfeeding and want to do it again, but my son won't latch again, so im trying to pump. My nipples hurt TREMENDOUSLY the more I pumped. Yikes...
