Pregnant?

My husband and I are trying to have a second baby (our first is 14 months). We recently tried this past week when I was most fertile and since then I have experience a lot of cramping and bloating. My period isn't due for 2 weeks and I rarely cramp during my period, let alone 2 weeks prior. I'm also not bloated often. On day 3 of trying I also had spotting a pinkish blood. Anyone experience similar feelings? Too early to be pregnant? Thank you!
