My question is , my period ended the 25th of September and i've been sexually active with my boyfriend since the 26th and its been unprotected . I've been experiencing some light menstrual cramping since last thursday , its not everyday that i feel them , but when i get them i feel like they're contractions . I do have a three year old son and even if I was possibly pregnant , i wouldnt know the symptoms because its been so long , i am on prenatals right now because were TTC . I just need a doctors opinion on whats going on with my body right now , this has never happened to me before even with my first born .
