So me and my boyfriend recently started trying to having a baby. This was the first time we had unprotected sex since we started dating...The moment we both climaxed it was amazing!!! Well as soon as we got up my body felt “Weird and different”...ever since then, i have been having alot of lower back pain and headaches and nausea (mainly after eating) and slight cramping off and on(no spotting just yet and no tender boobies(but i think the have gotten bigger))...i know it’s probably to early to tell (its only been 5 days so far) and im not supposed to test till the 9th but its killing me having to wait lol hopefully i can get my BFP when i test..if i dont, what can i do to increase my chances of getting pregnant in the future???
