Is if worth buying a first response/need help and support

Emma

So I tested this morning with a test that was need 25 in the urine , I know the first response need less , is it worth spending the money getting one ? I’ve been feeling really sick and crampy on and off all week , bit of an active bowel and boobs feel full and for the first time in about 4 years I was asleep before 9:30pm i was exhausted!I’ve had frequency to pee a lot ! I tested today and it was negative / possibly vvvvfl with a test that needs more hcg I didn’t know whether it was worth buying a first response to see ! With my first pregnancy I was 2 weeks late before I got my positive ! I knew I was pregnant despite he negative tests I just knew ! This time I kind of feel the same , I feel like I’m pregnant ! I just don’t know whether to spend the money on the test , or hold of longer ! I don’t want to set myself up for a fail I just want this so bad:( I know although I feel pregnant that I’m probably not and I’m just going to be sad :( sorry for the long post ! I don’t know who to talk to ! Everyone I speak to ( close friends ) keep saying stop trying it will happen , but what they don’t realise is that with a 3 year old and both working full time , if we didn’t actively “try” then our chances would be slim to none ! What would you do ?
