Hi can you help me? I am very confused. I was on my period and it ended the 10th march, I had unprotected sex on the 18th march and since then I have been bleeding firstly on the 25th March which was very light pink in colour and last only 2 days, i have been really tired very bad cramps in my stomach and feeling sick. I have done a pregnancy test and it came up negative twice, do you know if i can be pregnant? Also yesterday i started to bleed again this time was very dark brownish with small clots, could I be pregnant or worse miscarried? Any help would be greatly appreciated as I feel very off.
