If you are breastfeeding at 3 months old then you are already giving him foremilk with more calories now.
Yes, you should take a pregnancy test.
Every pregnancy is different.You may start having a few symptoms (i.e. breast tenderness,possibly frequent urination) as early as 2 weeks into the pregnancy or symptoms might show up much later.Some women experience little or no symptoms at all.
The main symptoms aremissed period,nausea with or without vomiting,tiredness,dizziness,breast changes and breast tenderness, andfrequent urination.The main symptoms of pregnancy are nausea, dizziness, heartburn, missed period, strange food cravings, bloated stomach, mild cramping, gassy, sore breasts and having light implantation bleeding.
Then you're not pregnant. Those are just PMS symptoms (except foot pain, which isn't really a pregnancy symptom either until about 32+ weeks)
All of these symptoms are symptoms of pregnancy, but this does not give you a 100% certainty that you are pregnant. It can be a coincidence that all these factors are happening at the same time, but because all of these are common with pregnancy, it is safe to presume that you are pregnant.
You still could be... It could be implantation bleeding and NOT your period... You should take a pregnancy test just to be sure.
You should go to the doctor immediately. Could be having a miscarriage. Or, pregnancy symptoms are very similar to period symptoms. Did you start your period?
Can you have pregnancy symptoms in first week after having sex
No, but, it would be called an "Ectopic pregnancy". It is usually diagnosed within the first 2 months of pregnancy, possibly before you know you are pregnant. The symptoms may be mild or they may be severe and dangerous. They can be the same as the symptoms of early pregnancy or other less serious conditions. Possible symptoms of an ectopic pregnancy are: 1. missed period or abnormal bleeding 2. pain in the lower abdomen or pelvis 3. symptoms of pregnancy such as breast tenderness or morning sickness.
I think you go to the doctor to have a blood test.
Some women report having symptoms this early.
Someone should take a pregnancy test when they feel they have symptoms of being pregnant. That is such as having food cravings, gaining weight, feeling contractions, etc.
