NEED HELP ASAP!!!

Erin • Mon, Mar 17 2014 • My partner and I are trying for our 2nd baby, firstborn (Kayden) had a CHD and sadly past away at 2 months old.

2 nights ago my partner and I were "baby making" and I started bleeding (wasn't due my period, had it a weeks before) and I've had horrible cramps since, took a test just now and it had an obvious line and a smeared one, is it worth going out and spending £15 on a digital one?!
