im having similar problems except i had my daughter almost 7 months ago and im having little fluttering in my tummy which im freaking out about, and i have yet to have a period i have not had a normal period since before i found out about my daughter and the last time i had sex was about 6 months ago.
try to relax and let nature take its cause if we listen to our bodies too much it sends the wrong messages Iam not just waffling this is from personal experience. Preg symptoms and af symptoms are almost very identical so its difficult to differentiat sometimes. There was a time very recently i wanted to conceive very much, and i felt almost preg for the whole month i was feeling sick nauseated not just imagining but it was really happening , very tired and lethargic , moody and my breasts were very sore , heavy and tender(they still are though)and i took loads of hpt and all of them turned out negative. However the message iam trying to send is that please dont be anxious as I was. But at at the same time some people can feel this things from the word go. Good luck anywhere by the way i have a daughter and with her preg i did not feel anything at all but please remeber each preg is different so as each individual i hope iam not being too negative i just wanted to share an honest opinion.
Cheers
My bbs tend to get veiny and sore before AF, but if yours do not or if it's more so this time than usual, then that could definitely be a sign. If you're really antsy you could probably get an early test, but, from my experiene, it's usually just best to wait it out until you know for sure that you are late and then test.
Baby dust to you!
