I've been having periods that have only lasted for two days with brown spottings after, the first came on the expected date 6th Oct, the second was on 13th Nov, the third came on the same date the following mth i.e 13th Dec while the fourth came on 15th Jan. All lasted for 2 days with brown spottings coming after. I've been having pregnancy symptoms like big and sore breasts, white discharge, feeling sick 1st thing in the morning, nausea, headaches, dull lower abdominal aches (not during the periods) accompanied by some sharp pains in the lower abdomen, faint feeling, heart burn, frequent urination in the first 3 mths, metalic taste in my mouth and my tummy has increased. If i'm pregnant I should be in my 19th week but I went for a blood PT when I was supposed to be 11 weeks old but tested negative. I don't understand what's going on, I lost a 4 mth old pregnancy few months ago. I don't know what to do please I need ur advice.
