Vent!!

K
I just need to vent! I am 7 days late! Had three faint but positive tests but also 4 negative tests one FRRR and one digital! I've been patient and took one now but my first wee I used a blooming dodgy test.  So I took one now and blank not even a hint of a line. I'm crying!! 18 months ttc no 2 and our first was a struggle. He's two a month today. And I keep being told you have one you won't get upset if you can't have another! But I am!! I always wanted 3 and feel guilty for not being able to give our son a sibling! All my friends I was pregnant with are now proud parents of two and I'm feeling low! 
I am so grateful for my boy and if it is my lot then great! I'm just so disappointed for my plans. One is a blessing but I don't find it fair that some people just fall so easy!!! I'm trying to lose weight and everything but I have pcos and I'm just bitter!
