### input:
I have been trying to get pregnant but we only just started trying about 2 weeks ago.  We had sex 3 times without a condom.  Now for the past 4 days ive been experiencing lower back pain and abdominal pain. It feels like my period will be here tomorrow but it just never comes. But i also feel its way too soon to have any pregnancy symptoms.

### output:

Hallow Dear, The cardinal and first symptom of pregnancy is missed period. Though it is not absolutely clear from your history whether you have missed your period or not, the impression I got is you have not missed period. Even if you have missed period, the other following symptoms start appearing after about 10 days or so after missed period. These symptoms are:1. Nausea & Vomiting and Pica2. Frequent urination3. Breast symptoms: Engorgement with tenderness, dark discoloration of nipples and areola with increase in areolar size, Montgomery's tubercles under areola and secretions from the nipples. Pain is not a feature of normal uneventful pregnancy without any risk. Appearance of pain anytime during pregnancy is indicative of some risk to the pregnancy. If you have missed your period, you can confirm the diagnosis of pregnancy by performing pregnancy test on overnight first early morning urine sample 8-10 days after missed period. Earlier these tests may give false negative results. Alternatively, you may opt for Beta Chat Doctor test which gives reliable results even few days before missing period. Abdominal pain with low backache is a classic feature of amoebic colitis which can be treated with Metronidazole. In this condition, the stools are stained with blood and/or mucous. I hope this helps you.
