I wish i wish i wish....

I realluly just need to express my feelings because i dont have anyone i can talk to:

Latley I've been having some serious baby fever and just recently I just happened to have sex during my fertile time. Now, it wasnt planed because SO doesnt want kids...(its complicated bc we both already have a child from a previous relationship and he tells me maybe in the future) Anyways, after we had sex I felt super differnt- really off so I started looking into my period stuff (i didnt chart or keep track before hand)and long story short we may have concived a child.

My concern is that the symptoms I am "showing" are just PMS related. Im due to AF on the 21st of July but a couple days after the sex thing happened I started to have some weird feelings/symptoms going on that I don't normally have until about 5-6 days AF. Now, most my stuff is normal PMS signs like light cramps, super moody ect but then theres this light headedness which has been going on since 2dpo which Ive never felt before in my life before AF, little headaches, i had a weird bubbly feeling in my stomach for about 24 hours about a day ago along with being super gassy but i had constipation and then diarriah and my stomach still feels off and im still gassy but its not bubbly and then to top it off i got really really bloated which also happens before AF only this time it lasted for about 24 hours and went away. Anyways you guys...i think I might be preggers but then I dont think I am at the same time. And i know its to early to tell but i still have my hopes up and i know if im not im gonna be so disappointed. And I cant TTC bc SO doesnt want to yet and im not about to do it behind his back and im just at al loss here

I went back to feeling normal today besides very light cramping...

How do you guys deal with your SO not wanting kids but you do so bad? And how do I make sure that I dont get my hopes up? Im just feeling super sad today :(

Its all i have been thibking about since the 6th of this month and the closer I get to AF the more I want to believe i wont get it.

Ugh sorry guys im just blah :( help!
