So my two and a half year old son keeps laying on my stomach like with his ear to stomach and kissing my stomach lol its so cute but a little irritating too cause im 9 DPO and im waiting to test my period is suppose to be here on the 20th i been having alot of symptoms but those dont even matter because it seems like they both have the same symptoms ... When should I test? Do you think kids really know before the BFP ? I cant wait now to test OMG HE IS GIVING ME SUCH HOPE ❤️❤️👍🏼👶
