So I had unprotected sex 5 days before my period, I had my period although it was slight different it was normal flow but 3 days into it it stopped completely for that day then started again and that was it. No pain no nothing. So I just let go of the I might be pregnant thing cause obviously I had my period for the month. Buuuut, 3 days after I finished my menstrual cycle I started feeling period like cramps on my stomach and started feeling lower back pain also just like if I was on my period but no blood it's not painful it's just a uncomfortable kind of feeling. Not to mention that I was sick.. with a sore throat and a stuffy nose. (I'm not the type to get sick like I was.. and with a dry cough! That's just not me) I'm feeling very nauseous to the point where I can't even see food. Been feeling dizzy, headaches all throughout the day, I'm just not feeling myself. Again with the cramps, headaches, nausea, dizziness, CONSTIPATION also, and feeling tired all time, it's been 6 days and it hasn't gone away. I told my mom what I've been feeling and she mentioned to me that there has been cases where woman who have been pregnant and still had their period some throughout pregnancy.. I'm just so confused.. and scared I have no idea what's going on with me.. I've also done research and it all points to pregnancy, but I'm still with the big no no because I had my period.. I just don't know.
