I got dark blood discharge and I'm having pain on the side of my abdomen with breast pain

Hi dear. I am happy that you chose a public platform to resolve your query. I hope you will get a good answer here. I am a mother myself so I will try to give you the answer as much perfect as I can. Some people say they feel certain they’re pregnant at the moment of conception, thinking they can already feel the very first signs of pregnancy. While for others it may take a positive pregnancy test – or two – to convince them. Missing your period and feeling a little ill are common early signs of pregnancy – but there are many other early pregnancy symptoms that may indicate you are pregnant which is tender, swollen breast. Your breasts may provide one of the first symptoms of pregnancy, fatigue, slight bleeding or cramping, nausea with or without vomiting, food aversions or cravings, headaches, constipation and mood swings. If you see these symptoms the better thing will be to contact a good gynecologist. My best wishes are for you.

Well i have two kids already and feel very sure of being pregnant but my test don't usually show for the first few months my husband is suffering with heartburn since last night but i want to be sure because i had a miscarriage almost 3 months ago and want to prevent it from happening again
