Well first all i had a tubal Reversal on the 22nd of January! Ok i had intercourse around the first of February, i got my period on the 14th and whats weird is i still have a flow. I always am so light and done within 5 or 6 days. My flow is kinda red still but i dont need. Tampon. Only when i wipe you see. Well im vomiting im feeling anxious. And my last pregnancy i had my period when i was pregnant, of course period only lasted 4 days then. Its weird I’ve been feeling weird for about 3 days now. Even want to cry! Thats not me at all.
