TTC #2

Carita
Hey everyone... I'm TTC #2 as of 8/22. The first baby is now 3 and was totally unexpected but conceived around this time of year. We BD quite often and I know how to check for CM but I'm clueless on checking position of cervix. Not sure if that helps in the long run but any and all tips would greatly be appreciated. Also...So I'm 6dpo and I'm cramping, gassy and with tender breasts. BD several times during the high peak days. How soon can I test and should I be concerned about the cramping?! (By the way, the cramping is not in the lower abdomen , like cycle cramping...more around my navel) ALL feedback greatly appreciated... Cycle buddy???
